The 1968 United States presidential election in Iowa took place on November 5, 1968, as part of the 1968 United States presidential election. Iowa voters chose nine representatives, or electors, to the Electoral College, who voted for president and vice president.
Iowa was won by the Republican candidate, former Vice President Richard Nixon, with 53.01 percent of the popular vote, against the Democratic candidate, former Senator and incumbent Vice President Hubert Humphrey, with 40.82 percent. American Independent Party candidate George Wallace performed decently, finishing with 5.69 percent of the popular vote.
Nixon's victory was the first of five consecutive Republican victories in the state, as Iowa would not vote for a Democratic candidate again until Michael Dukakis in 1988, after which it leaned Democrat until 2016, although George W. Bush narrowly won the state over John Kerry in 2004.
