1968 United States presidential election in Illinois

The 1968 United States presidential election in Illinois took place on November 5, 1968, as part of the overall 1968 United States presidential election. Illinois voters selected 26 electors to represent the state in the Electoral College, which would then choose the president and vice president.

Illinois had been consistently Republican during the "System of 1896," with the exception of a few areas in the southern part of the state that sympathized with the Confederacy during the American Civil War. However, starting from the New Deal era, Illinois became a crucial swing state, having voted for the winner of every presidential election since 1920.

Like other states in the Midwest, Illinois had been severely affected by racial tension during the presidency of Lyndon Johnson. This situation played a role in Charles H. Percy's comfortable Senate win, as he defeated Democrat Paul Douglas. Illinois, particularly the Metro East region, was affected less by racial tension compared to states located to its east.

By the time the election campaign was in full swing at the end of the summer, Democratic nominee and incumbent Vice-President Hubert Humphrey was clearly in serious trouble, and early polling suggested he would have little chance in the state. Humphrey was further hindered by the refusal of Chicago Mayor Richard Daley Sr. to help him.

The failure of Nixon’s “50 State Strategy” in 1960 led him to focus on a few electoral-vote-rich states, of which Illinois was one of the most critical. Humphrey lost further in polling during September, and at the end of the first week of October Nixon had a substantial lead. Nevertheless, when the Vice-President campaigned alongside rival former and future Alabama Governor George Wallace, he would gain sharply so that state became extremely close at the beginning of November.

Johnson had already ruled himself out for the nomination.

Analysis
Republican candidate Richard Nixon won the state of Illinois by a narrow margin of 2.93%. The winning of Illinois was the moment that sealed a close and turbulent election for Nixon, who in the last counting did much better in massively populated Cook County than Goldwater or Nixon himself in 1960.

Nixon won ninety of Illinois’ 102 counties, with Humphrey winning only Cook and St. Clair Counties with absolute majorities, although he carried several other Metro East and southern Illinois counties where he was helped by the backing of unions and a strong vote for Wallace taking much Nixon support. Wallace’s segregationism also went down very poorly in many cities of that latter urban region.

Nixon's victory was the first of six consecutive Republican victories in the state, as Illinois would not vote for a Democratic candidate again until Bill Clinton in 1992. Since then it has become a safely Democratic state. Nixon became the first ever Republican to win the White House without carrying Rock Island County, as well as the first to do so without carrying Macon County since Abraham Lincoln in 1860, the first to do so without carrying Pulaski County since Ulysses S. Grant in 1868, the first to do so without carrying Alexander or Cook Counties since Rutherford B. Hayes in 1876, the first to do so without carrying Fulton County since Benjamin Harrison in 1888, and the first to do so without carrying Christian County since William Howard Taft in 1908.
