Donald Trump and Hillary Clinton are locked in a dead heat in Iowa, according to a new poll released Monday.
The survey by Simpson College and RABA Research, a bipartisan polling firm, showed Trump with 40%, Clinton with 39%, Libertarian Gary Johnson with 10%; Green Party candidate Jill Stein with 3%, and 8% undecided. The difference between Trump and Clinton is within the poll's margin of error, which is plus or minus 3 percentage points.
If November's general election were held only between the two leading candidates, Trump would receive 43% and Clinton 42%.
The poll included 1,054 interviews with Iowa voters conducted Sept. 6-8 via automated phone and Internet surveys.
Iowa is considered a battleground state in the presidential election, and Trump and Clinton both have both placed a priority on winning Iowa's six electoral votes.
Negative views are clearly a factor in the presidential campaign in Iowa, the poll shows. While 57% say they are voting “for” their candidate, 41% are turning out to vote “against” a candidate.
The poll also showed 44% of Iowa men favored Trump compared with 37% of Iowa women. Clinton was supported by 34% of Iowa men compared with 43% of Iowa women. In addition, Iowa evangelicals were far more likely to support Trump than Clinton, favoring him by a 56% to 25% margin.
Meanwhile, Trump was supported by 36% of Iowans who had attended college compared with 42% for Clinton and 13% for Johnson.
Trump is scheduled to return to Iowa for a campaign rally at 7 Flags Events Center in Clive at noon Tuesday, followed by a private fundraiser at a West Des Moines restaurant. The billionaire businessman spoke in Des Moines at the Iowa State Fairgrounds in late August at Sen. Joni Ernst's Roast and Ride. Meanwhile, Clinton campaigned on Labor Day on the Illinois side of the Quad Cities at an event attended by many Iowa Democrats and union activists from Davenport and Bettendorf.
An Iowa poll released Sept. 2 by Emerson College had found Trump leading Clinton 44% to 39% with Johnson at 8% and Stein at 1%. Eight percent were undecided.
