These maps show how Iowa voted in the 2020 election

There was little waiting for results after polls closed on Election Day for most races in Iowa. President Donald Trump had a solid victory in the state, holding onto counties that voted for him in 2016. U.S. Sen. Joni Ernst also held off a hard-fought challenge from Democrat Theresa Greenfield. 

In U.S. House races, three of four elections for Iowa's congressional districts are decided with one big upset: Iowa Republican state Rep. Ashley Hinson defeated incumbent Democrat Rep. Abby Finkenauer in the U.S. House District 1 race. The undecided race: The U.S. House District 2 race between Rita Hart and state Rep. Mariannette Miller-Meeks is still too close to call, separated by fewer than 300 votes.
