On January 31 McCain received the endorsement of California Governor Arnold Schwarzenegger and began campaigning with him. This was a key endorsement, as California was one of the Super Tuesday states and had more delegates than any other state. The same day, Governor Rick Perry of Texas threw his support behind McCain. Perry had previously been a Giuliani supporter, while Schwarzenegger had refrained from endorsing either McCain or Giuliani because he counted both men as friends. Meanwhile, Romney, still burning about McCain's Iraq withdrawal timetable charge, compared McCain to disgraced former President Richard Nixon, saying that McCain's claim was "reminiscent of the Nixon era" and that "I don't think I want to see our party go back to that kind of campaigning."
