I don’t know much about Lovitz, but I’ve always suspected there are a lot more “liberals” in Hollywood who are fiscally more conservative, but it is the “go with the flow” attitude of Hollywood and the social issues that make them stay with the liberal party line. You have your true believers like Clooney, but a lot of people who moved there and/or aren’t into politics that much.
Plus they have to be afraid to speak up much. I even suspect some that say they are for Obama in public aren’t.
It really shows that having only 2 real parties is really clunky.
