California Primary 2020: Why independents can vote for Democrats, but not for Republicans
The American Independent Party (AIP) is a far-right political party in the United States that was established in 1967. The AIP is best known for its nomination of former Governor George Wallace of Alabama, who carried five states in the 1968 presidential election running on a segregationist platform against Richard M. Nixon and Hubert H. Humphrey. The party split in 1976 into the modern American Independent Party and the American Party. From 1992 until 2008, the party was the California affiliate of the national Constitution Party. Its exit from the Constitution Party led to a leadership dispute during the 2016 election.
