that Schwarzenegger might run for the United States Senate in 2010, as his governorship would be term-limited by that time. Such rumors turned out to be false. Wendy Leigh, who wrote an unofficial biography on Schwarzenegger, claims he plotted his political rise from an early age using the movie business and bodybuilding as the means to escape a depressing home. Leigh portrays Schwarzenegger as obsessed with power and quotes him as saying, "I wanted to be part of the small percentage of people who were leaders, not the large mass of followers. I think it is because I saw leaders use 100% of their potential – I was always fascinated by people in control of other people." Schwarzenegger has said that it was never his intention to enter politics, but he says, "I married into a political family. You get together with them and you hear about policy, about reaching out to help people. I was exposed to the idea of being a public servant and Eunice and Sargent Shriver became my heroes."

Because of his personal wealth from his acting career, Schwarzenegger did not accept his governor's salary of $175,000 per year.

Giuliani dropped out of the presidential race on January 30, 2008, largely because of a poor showing in Florida, and endorsed McCain. Later that night, Schwarzenegger was in the audience at a Republican debate at the Ronald Reagan Presidential Library in California. The following day, he endorsed McCain, joking, "It's Rudy's fault!" (in reference to his
