I don’t even consider Schwarzenegger moderate. He’s way left of center. Listen to him plead the case of the leftist agenda points.
Arnold did veto some of the worst ‘Rat legislation, but overall he just lets them do what they want.
After conservatives and voters abandoned him in 2005, he's done all that is politically expedient to stay in office. In that sense he's been exactly what he always claimed to be: the People's governor. He's not an ideologue, he's a populist.
