Susan Sarandon & Tim Robbins are two, as well. But, they usually leave the politics at the studio door. Not always. But, usually. However, I think it's the insistence of their politics that have so many studios blacklisting them. Same with guys like William Hurt and Ed Begely, Jr. Will Ferrell is falling into that trap, as well.
Interesting to note: Kelsey Grammar is a hardline Republican. I think so many people get him and his character of Frasier Crane mixed up. But, check out some interviews with him on the subject...
