WATCH: Trump ad accusing Hillary of demonizing "hard-working Americans" who support him

Donald Trump unveiled a new television ad today ripping Hillary Clinton for saying half of the GOP candidate’s supporters fit in a “basket of deplorables.”

The 30-second spot will air in the battleground states of Ohio, Pennsylvania, North Carolina, and Florida and will target “hard-working Americans she viciously demonized,” said Jason Miller, Trump’s senior communications adviser, in a statement.

At an LGBT fundraiser in New York City last Friday, Clinton described Trump’s supporters as “racist, sexist, homophobic, xenophobic, Islamaphobic—you name it,” she told a packed audience. “You know, to just be grossly generalistic, you could put half of Trump’s supporters into what I call the basket of deplorables.”

Her remark outraged conservatives and the Trump campaign, which said Clinton “revealed just how little she thinks of the hard-working men and women of America.”

Clinton expressed regret Saturday for half of her comment, “Last night I was ‘grossly generalistic,’ and that’s never a good idea. I regret saying ‘half’ – that was wrong,” she said in a statement that also vowed to call out the bigotry and racist rhetoric coming from the Trump campaign.

Much of the criticism directed at Clinton was for overestimating the percentage of bigots in Trump’s base, as opposed to the harsh words she used to characterize them:

As I argued, "half" was a mistake. But underlying argument is 100 percent right: https://t.co/mBBLXqll8Y https://t.co/NaxOIA6vx0

While Clinton walked back her comment, polls indicate she was not far off in her characterization. According to polls culled by The Washington Post's Greg Sargent, a majority of Republicans back Trump's proposal to temporarily ban Muslims from entering the country; more than half also support mass deportation.

These polls show that Trump has successfully incited anger towards immigrants. In the new ad "Deplorables" that debuted today, the Trump campaign implies "hard working people like you" fit in Hillary's proposed basket.
