Andrew Breitbart has a quite amusing column in the Washington TImes
LOS ANGELES — The conventional wisdom is that Hollywood has never before been so gaga over any candidate as she is now for Democratic Sen. Barack Obama. In addition to raking in Oprah-level campaign cash, Mr. Obama is making Sen. John McCain, despite the Republican's comedic turns on "Saturday Night Live" and in "The Wedding Crashers," look like an out-of-it grandfather.
While it is true that the ratio of Obama-to-McCain bumper stickers in West L.A. is about 250-to-1, there are untold closet Republicans in the entertainment industry who dare not advertise their beliefs in movie studio parking lots. (Unfortunately, car keying is a tactic wielded liberally by the self-described "tolerant.")
But in this land of superficiality and augmented assets, the inconvenient truth is that, in Hollywood, absolute conformity to the Democratic Party is a well-constructed facade. The environment is not so much unfavorable to the Grand Old Party as it is utterly totalitarian. There's simply no lifestyle choice that receives a worse response at dinner parties. . . .
