Governor Schwarzenegger has said he would not make an endorsement in the Republican primary, but on Thursday the Governor endorsed John McCain, giving a boost to the Republican presidential front-runner six days before California's primary. Schwarzenegger says McCain's ability to work with both Democrats and Republicans was key in his decision to endorse the Arizona senator. Schwarzenegger's endorsement of McCain over Mitt Romney comes after the former Massachusetts governor lost the Florida primary vote to McCain on Tuesday. California is a large prize among the 24 states that will hold their primary elections next week on "Super Tuesday." Candidates secure three delegates for each of the state's 53 congressional districts they win in the primary, in which only Republicans can vote.
