ABC News projects Donald Trump will win in Iowa.
The coronavirus was surging in Iowa ahead of Election Day, as the presidential proving ground is also in the middle of the fight between Democrats and Republicans for control of the Senate and White House.
Polls are open from 7 a.m. to 9 p.m. CT statewide. The state has six electoral votes at stake in the presidential race.
Trump last visited the state in October, and also held a rally in neighboring Omaha, Nebraska, in a bid to reach voters in western Iowa.
Sen. Joni Ernst, R-Iowa, is running for reelection against Democratic businesswoman Theresa Greenfield, and will face a difficult path to victory should the president underperform.
Democrats are expected to hold three of Iowa's four House seats, while Republicans are favored to retain the seat long held by Rep. Steve King, a Republican defeated in a primary this summer by Iowa state senator Randy Feenstra, after facing criticism for comments about white supremacy.
