From the LATimes today, on why Hollywood isn’t too interested in getting involved in local races:

Today, the reasons for Hollywood’s disengagement are not all that different, according to Lawrence O’Donnell, an MSNBC political analyst and a writer and producer for “The West Wing.” Like many of the city’s wealthiest residents, he said, the Hollywood elite doesn’t rely on local government for much.
“We have to remember, these people generally do not use the public school system,” he said. “They generally do not rely on the local police force for their security. They have their own … that are much better and more efficient.”
