Nope. Arnold is pissed that he lost the election last year, so he is running Left. This is why I never voted for him. He is an opportunist, and will shift with the political winds in order to make some "successes".
Sorry, that excuse doesn't work. Before the election, he made his support for a minimum wage increase known. It had nothing to do with the election and everything to do with his lack of fiscal conservatism and economic savvy. (Go Here)
