Not only is it the latest poll to show Trump “surging” in Iowa and nationally, but it was taken before Clinton “insulted tens of millions of hardworking Americans and veterans supporting Donald Trump’s candidacy by calling half of them 'deplorable' haters and calling the other half too stupid to make up their own minds of who should be our next President.”

The Clinton campaign did not respond to a request for comment.

The results also indicate that Iowa voters are not entirely settled with the top two choices, Bardwell said. While 57 percent say they are voting “for” their candidates, 41 percent are turning out to vote “against” the other side, affirming a certain polarization among the electorate as a whole.

“As of now, both candidates have a very high floor when it comes to early support,” said RABA Research partner Brad Anderson, a Des Moines Democrat. “If Democrats continue their historically effective turn-out-the-vote program, it could be enough to make the difference in what is shaping up to be an ultra-close race.”

The poll found that 57 percent of Iowans said the third-party candidates should have a spot on the debate stage this fall alongside of Trump and Clinton.
