But a closer look at the numbers is not so reassuring for the president. Much of the growth in the Latino population has occurred in California, Texas, Illinois and New York, which are not likely to be competitive come Election Day. While the Latino population is growing fast, the Latino electorate is not. Compared to other ethnic/racial groups, Latinos are more likely than whites to be under 18 years of age or to be non-citizens. “For every 100 Hispanic residents in the United States, only 44 are eligible voters aged 18 and over and U.S. citizens,” notes William Frey, demographer at the Brookings Institution. “In contrast, 78 of every 100 white residents are able to vote.”

Frey has argued that “minorities will decide” the 2012 election, but he acknowledged in a telephone interview that Latinos, as a group, do not loom large in most of the dozen battleground states. According to his analysis of 2008 and 2012 census data, Latinos comprise less than 2 percent of the voting population in Ohio and Virginia. In North Carolina, New Hampshire and Iowa, they comprise 3 percent or less of the electorate. In Wisconsin, they comprise 3.1 percent of voters, down from 3.7 percent in 2008.  Even if Obama won an additional 10 percent of the Latino electorate in these states over what he did against McCain, the increase would be smaller than his margin of victory in 2008 in every case.

That leaves Florida, Nevada, New Mexico and Colorado, where the Latino vote appears to be large enough to be decisive in a close race. The good news for Obama is that many of those states could make the difference between winning and losing the White House. The bad news is that the outlook is distinctly less favorable to a more decisive Latino role than 2008.

As Frey has noted:

Minorities mattered in 2008 for three reasons: first, their relative sizes compared with whites increased in each state; second, their enthusiasm for the Democratic candidate was greater than in 2004; and third, white support for the Republican candidate (John McCain) waned in comparison to the previous election.

None of those factors appear to hold true in Florida. Latinos comprise about 15 percent of the state’s voters, unchanged from 2008. While a Gallup swing state poll earlier this month found Democrats are more enthusiastic about the president than Republicans are about Romney, they are also less enthusiastic about Obama’s candidacy now than they were in 2008, especially minority voters. As Real Clear Politics  has noted:

Enthusiasm among non-white voters is down from 74 percent at this point in 2008 (vs. 58 percent for whites) to 48 percent today (the same goes for whites). And, indeed, in 2010, African-American turnout reverted to the mean. If this occurs in 2012, Democrats will need a massive surge in the minority population elsewhere to make up for this regression.

The most likely place for this to occur is within the Latino community. That population grew smartly over the 2000s. But — much less remarked upon — the Latino electorate did not. Indeed, since 2004, it has been almost perfectly flat, and it contributed only marginally to the decline of the white vote from 2004 to 2008.

Only in the three swing states of the Southwest — New Mexico, Nevada and Colorado — does the Latino vote seem big enough to be decisive. In New Mexico, Latinos are 38 percent of the electorate, down slightly from 2008. In Nevada, Latinos are now 17.3 percent of all voters, up from 13.3 percent from four years ago. And in Colorado, Latinos are now 12.1 percent of all voters, up from 11.3 percent in 2008.  Only in these states does the combination of the size and growth of the Latino electorate and Obama’s edge on Romney appear capable of giving him a margin of victory he might otherwise lack. In the rest of the swing states, he’s going to need something else.

King suggested lazy immigrants should be avoided as well. “You get the pick of the litter and you got yourself a pretty good bird dog. Well, we’ve got the pick of every donor civilization on the planet,” King said. “We’ve got the vigor from the planet to come to America.” The liberal research group American Bridge captured the comments:

Lately, however, King has backed off his inflammatory rhetoric, thanks to a tough challenge from Democrat Christie Vilsack. His bird dog comments suggest, however, that his mouth will continue to dog him.

Update: In a statement, Vilsack’s campaign said, “If we’re going to have a real discussion on immigration, we should start by acknowledging that immigrants are human beings. Iowans are taught in their community, in their church, and at the dinner table to respect each other, not to compare people to dogs. People expect a serious discussion between candidates and that’s what we’re committed to.”

The Romney campaign’s response has been that immigration is irrelevant to winning over Latino voters — jobs and the economy are the only things that matter. But his speech this week underscores just how difficult an argument that will be for him to make: In the past, the Latino Coalition has argued that immigration reform is part of a pro-business platform, not separate from it.

These days, the only immigration issue the Coalition mentions on its website is the “Mexican Trucking issue.” But the group aggressively advocated for comprehensive immigration reform under President Bush. In 2007, the Coalition’s president slammed “far right extremists” who opposed “common-sense [immigration reform] legislation that is so important for the security and economic vitality of our country.” The group “urge[d] Speaker Nancy Pelosi (D-CA) and the Democratic leadership in the House to demonstrate courage and leadership on this issue and take on immigration reform,” saying Pelosi could pass a bill “without the level of Republican support she is demanding.”

In the 2008 GOP primary, the Latino Coalition favored Rudy Giuliani — a veritable leftist on immigration reform compared to most Republicans — with the former New York mayor capturing 64 percent of the vote in a straw poll of the group’s members. Romney apparently finished behind Sen. John McCain and former Sen. Fred Thompson, as his name was not mentioned in the statement.

Meanwhile, the Chamber of Commerce, whose grand D.C. offices will host the event Wednesday, also supported comprehensive reform under Bush, similarly seeing it as a boon for free market capitalism. The powerful business lobby still calls for “an effective and streamlined temporary worker program so that employers can hire immigrant workers” and “a pathway to legal status for undocumented workers currently in the United States.”

This was essentially Bush’s policy too. But Romney’s infamous immigration advisor, Kansas Secretary of State Kris Kobach, who authored the draconian anti-immigration laws in Arizona and Alabama, said his candidate would not support any kind of pathway to legalization for undocumented immigrants.

The Romney campaign briefly attempted to disown Kobach after Romney won the primary and the advisor’s utility was spent, but he may have to throw his entire immigration policy under the bus with Kobach if he hopes to win over the Latino business owners on Wednesday, let alone Hispanic voters more generally.

Since then, the adminstration has deported many fewer non-criminal aliens. But non-criminals remain the vast majority of those deported. And those with no criminal record now actually comprise a slightly larger percentage of those forced to leave the country than they did before Morton’s announcement.

In the three months before the policy was announced last summer ICE filed for deportation proceedings against 61,192 people of whom 15 percent had criminal records. In the first three months of 2012, ICE sought 37,659 deportations orders, 14 percent of which involved people with criminal records.

“The agency continues to be headed in the opposite direction of its stated goals,” said Susan Long, co-director of the Transactional Records Access Clearinghouse at Syracuse University, which collected the data from ICE via a Freedom of Information Act request.

The goal of prosecutorial discretion, Long said in a conference call with reporters, “was to target and bring before the court those with more serious criminal history. As yet we’re not seeing any change. They have not turned the ship around.”

The administration implemented prosecutorial discretion in response to complaints that young people with no criminal records continue to face deportation. But the new data will come as no surprise to student groups such as United We Dream, National Immigrant Youth Alliance and DreamActivist, which continue to highlight the cases of law-abiding young people facing deportation.

Rep. Luis Gutierrez, D-Ill., has championed the case of a South Carolina man, Gabino Sánchez, a married father of two, who was arrested for driving without a license last year and now faces deportation.

“Gabino Sánchez has lived and worked and raised a family here for more than a decade and it is not in anyone’s interest to have him deported,” Rep. Gutierrez told Fox News Latino on Tuesday after a deportation hearing in North Carolina.  ”I do not understand why ICE has not followed President Obama’s guidelines and decided to move on from this case to go after someone else, someone who is a threat to his community or a serious criminal.”

In response to the TRAC findings, Gutierrez  said, “The president should make sure the Department of Homeland Security is actually following its own rules and he should proclaim proudly and loudly that he will not deport another DREAMer or anyone else who fits the prosecutorial discretion criteria.”

“This is what immigration reform under Obama has gotten us,” says Abdollahi, who traveled to Tacoma to rally public attention to Luna’s case. “The right to spend up to $5,000 to get a loved one out of jail. When Obama says he isn’t deporting dreamers, he’s lying.”

“Marco Rubio is being a lot more authentic with us,” Abdollahi added.

The positive response of young immigrants  to Rubio’s still-vague alternative to the Democrats’ DREAM Act is central to the changing politics of immigration in the 2012 presidential campaign. In a series of meetings in Washington, Rubio is shopping for support, hoping to put forward a legislative proposal in the next few weeks. The Washington Post endorsed the idea on Monday.

By flirting with Rubio, the DREAM activists — representing an estimated 1 million young Americans, or “dreamers,” who are now barred from a path to U.S. citizenship — have wrong-footed the Obama White House and given pause to reelection campaign officials who had been counting on Latinos to fall in line with the president’s reelection. They have also caught the interest of Republican strategists worried about Romney’s narrowing path for victory in November.

Rubio is expected to propose the creation of a non-immigrant visa that would ensure undocumented young people who don’t have criminal records would not be deported and could eventually become citizens. The original DREAM Act failed to pass  the Senate in 2010.

“We are going to support whoever will come out and talk about the issue,” said Gabby Pacheco, a 26-year-old special education teacher from Miami and DREAM Act activist. “Rubio realizes this is key for us. Even if he is only doing it for political reasons, we’re willing to listen.”

The dreamers are backed by Latino Democrats on Capitol Hill, who feel betrayed by the Obama administration’s boasts of deporting a record annual average of 400,000 people over the last four years. After a friendly if inconclusive meeting with Rubio, Rep. Luis Gutierrez of Illinois told Politico his liberal allies  accused him of being the Florida senator’s new “best friend.”

The Obama White House hates the idea. Last week, presidential advisors Celia Munoz and Valerie Jarrett tried to discourage the dreamers from embracing Rubio’s proposal, saying it put at risk the original DREAM Act, which laid out a specific path to citizenship. According to the Washington Post, they had a meeting with DREAM Act-eligible students in Washington, arguing that “Rubio had not demonstrated he could win support from fellow Republicans and that the president would use his clout to push an immigration plan next year. ”

Pacheco, who attended the meeting, was not impressed with the White House appeal.

“You can’t wait until next year if you’re getting deported this year,” she said.  She described the White House officials as “very strategic” in their opposition to Rubio. She said the dreamers asked Munoz and Jarrett if the president could stop the deportations by taking administrative action that would not need to be approved by Congress, as Florida immigration activist Cheryl Little recently wrote in the Miami Herald.

“The thing that surprised us was they said no,” Pacheco told me. “They said, practically, ‘We don’t have the power to do this.’We’re trying to find out if that is true.”

It isn’t true, says Laura Lichter, an attorney in Denver and president-elect of the American Immigration Lawyer’s Association.

“The Obama administration  could certainly be doing more and better to improve the situation for DREAM Act students and to make immigration law and policy predictable and fair for everybody,” Lichter said in a telephone interview. “Whether they’re willing to do that in any way that might look like reasonable treatment for the undocumented remains to be seen.”

Presumptive Republican nominee Mitt Romney, who has advocated “self-deportation” for the likes of Abdollahi and Luna and the estimated 1 million DREAM Act-eligible students, is noncommittal about Rubio’s idea. Romney’s hard-line immigration advisor, Kansas Secretary of State Kris Kobach, initially rejected the suggestion as “amnesty,” but has more recently said he can “work with” the Florida senator, a nod to the growing realization that running on a platform of “self-deportation” is Romney’s ticket to self-destruction among Latino voters in November.

Whether Rubio’s gambit can sway Republican votes on Capitol Hill is doubtful. House Speaker John Boehner described passage of such a bill this year as “difficult at best.” Helping the undocumented is not a priority for most non-Latino voters, according to Republican pollster Scott Rasmussen.

While elite Republicans like Haley Barbour have said positive things about Rubio’s idea, the conservative blogosphere is notably unenthusiastic. The Weekly Standard touted Rubio’s recent foreign policy speech while ignoring his much-publicized idea of helping young undocumented Americans closer to home. The National Review hyped Rubio as a Romney running mate without taking a stand  on his proposal “to give the children of illegal immigrants a visa to continue their studies.” Talk radio stalwarts like Rush Limbaugh and Hugh Hewitt have yet to mention Rubio’s plan, while Mickey Kaus, the Daily Caller’s anti-immigrant blogger, notes conservative intellectuals can only agree to disagree on the issue.

If the Republicans’ intellectual base seems stumped by Rubio’s gambit, the Democratic incumbent comes off as arrogant. In a recent interview with Telemundo, President Obama said:

This notion that somehow Republicans want to have it both ways — they want to vote against these laws [like Arizona and Alabama] and appeal to anti-immigrant sentiment … and then they come and say, ‘But we really care about these kids and we want to do something about it’ — that looks like hypocrisy to me.

To the dreamers, Obama is just as hypocritical. “A lot of folks want us to be against  it,” Abdollahi said. “At the same time we hear from Obama administration that they’re not deporting dreamers. They’re tricking us. That’s what makes us supportive of Rubio.”
