As the presidential race heats up toward Election Day, Iowa is one of the battleground states in the nation that could help determine the Electoral College victory for one of the candidates. Since 2000, Iowa's six electoral votes have gone three times to the Democratic candidate and three times to the Republican candidate. The state went for Al Gore in 2000, then was won by George W. Bush in 2004. Iowa went to Barack Obama in 2008 and 2012 before being won twice by Donald Trump — in 2016 and 2020.
