Why did Alvin Greene win in South Carolina?
It might have been ballot order, but probably wasn't race
A detail from the campaign flyer for South Carolina Democratic candidate for U.S. Senate, Alvin M Greene. A reader writes:
I’m interested in exploring the SC Dem Party Chair’s claim that the winner’s ballot placement was responsible for Tuesday’s outcome. I know of some research that supports that claim (Brockman 2003; Koppell & Steen 2004 — gated pdfs), but I haven’t seen anything that could support Ms. Fowler’s claim that ballot position resulted in Mr. Green’s double digit victory. Even in an extremely low information election, the research I’ve seen shows no more than a low single digit effect.
Here’s a little background on Greene, and here’s another piece by Kosuke Imai and Daniel Ho on ballot order, which finds similar effects (1-3 points) in primary elections.
All I have to go on here is some guesswork, but it seems plausible to me that ballot order could be an important factor here. This was a very low information race, it would seem. Greene’s opponent, Vic Rawl, only raised $186,000 for his campaign, which isn’t much money for a statewide race. The low salience of the race is also evident in the roll-off: 169,542 voted in this race, versus 188,576 in the Democratic primary for governor.
And I’m not sure that the potential ballot order effect is implausibly large. Assume for the moment that voters were essentially choosing at random between the candidates. That would imply a 50-50 outcome. The actual outcome was 58-41, which only implies that 8-9 percent of voters were influenced by ballot margin.
Another question is whether there was any information on the ballot that might have cued voters to choose Greene over Rawl. I wondered whether S.C. voters might have inferred the candidates’ racial background from the names of the candidates. I looked to see whether there was any relationship between Greene’s percent of the vote in each county (data here) and the percent black in that county from the 2000 Census (data here).
There is a modest positive relationship, although it is not statistically significant. Ecological inference problems make this analysis suggestive at best: Analyzing at the county level can’t actually tell us for sure how individuals are voting. But still, I don’t see much happening here.
Other theories welcome in the comments, and see also Tom Schaller’s post at 538.
Rethinking the origins of the Tea Party
They're not so unfamiliar or brand-new
Mark Lilla’s essay, “The Tea Party Jacobins,” seeks to explain the origins of the Tea Party. I do not disagree the part of his explanation that emphasizes the most proximate causes — particularly the financial collapse, bailout, and health care reform. Nor do I disagree with his prognosis, which is that the Tea Party faces significant organizational challenges (see this earlier post). But Lilla believes the Tea Party also stems from a “populist mood that has been brewing for decades” and is a “manifestation of deeper social and even psychological changes that the country has undergone in the past half-century.” Here, I think he is quite wrong.

A political scientist's perspective on how journalists should approach the midterm races
Week before last I had a conversation with a Washington Post reporter whose beat for the 2010 campaign is voters. She’ll be traveling to districts and interviewing voters throughout the election. Here are some questions I suggested she might consider.
1. Will the “enthusiasm” gap in turnout persist, especially as both parties begin mobilizing their respective partisans in earnest?
2. There are aggregate relationships between economic growth (not unemployment!) and presidential approval on the one hand, and seat gains and losses by the president’s party on the other. How much will either factor change in the months ahead? (This wasn’t really amenable to her beat, so I suggested the next question.)

A study of New York Times coverage shows that the press loves to cover a natural disaster. For about a week
“American public attention rarely remains sharply focused on any one domestic issue for very long — even if it involves a continuing problem of crucial importance to society.” So wrote the economist Anthony Downs in 1972. He described the “issue-attention cycle”: “Each of these problems suddenly leaps into prominence, remains there for a short time and then — though still largely unresolved — gradually fades from the center of public attention.”

At last week’s Conservative Political Action Conference, Minnesota Gov. Tim Pawlenty called on the attendees to imitate the wife of Tiger Woods: “We should take a page out of her playbook and take a nine iron and smash the window out of big government in this country.”
