Arnold is pretty similar on most of these issues. I guess due to economic issues, where he was leaning more towards the right? Certainly people like him regard their party more of a vehicle instead of a master (using John Kasich's words).
I wish Obama would have nominated him to the Supreme Court in 2016. Likely wouldn't have been confirmed by Cocaine Mitch, but Sandoval may have been better than Merrick Garland.
I think Merrick Garland was a huge mistake. Obama should have nominated the first African American woman judge.
