In an interview with NBC's "Today" show that aired Tuesday and was taped earlier at the Stanford Mansion, Schwarzenegger was asked how he felt about those Republicans, including Limbaugh, who say he is only pretending to be a Republican.
"All irrelevant," Schwarzenegger said. "Rush Limbaugh is irrelevant. I'm not his servant. I am the people's servant of California. What they call me, if it's a Democrat or a Republican or in the center or I changed or this or that, that's not my bottom line. This is for them to talk about."
Then you can read what Rush said about it here. Rush's problem is that Arnold is a Republican but not a conservative. Arnold is said to care about the environment and health care and icky non-corporate stuff like that. Stuff that would take away from the rich. Conservatives put money before people. Generally, Republican people are not averse to engaging in practices that would benefit the greater good. It's only since neocons invaded the party that the tide began to change so drastically. Personally, I'd like to see all conservatives leave the Republican party. Are they so cheap that they can't start their own party? The more parties the merrier.
