In the 1968 Presidential election, Richard Nixon faced off against Hubert Humphrey and George Wallace.

The US presidential election of 1968 was held on November 5, 1968. Former Vice President Richard Nixon (Republican) won the election, by a narrow difference over Vice President Hubert Humphrey (Democrat).

Nixon conducted a campaign that promised to restore "public order." Some consider the 1968 election an election that broke with the so-called New Deal Coalition that had dominated presidential politics since 1932. It was also the last election in which the two candidates were vice presidents.

The election also included the former governor of Alabama, George Wallace, who ran as the candidate of the new American Independent Party. As Wallace's campaign promoted racial segregation, he proved to be a formidable candidate in the South; no "third party" candidate has won electoral votes since then.
