There are a smattering of Ivy League grads among the Hollywood A-List. Not sure how much they are into politics though. I would be surprized though if John Travolta were a Democrat same with Tom Hanks.

Did check-- Tom Hanks is a Democrat-- Tom Hanks - Wikipedia, the free encyclopedia

Cannot really get an answer with John Travolta.

I would though be more interested in what some celebrity's politics were than some Ivy League Philosophy, Law, or Literature professor's opinion on politics. Some celebrities are out in the world meeting a wide range of people with many different opinions. They could have some insight on what a politician like Barack Obama, William Clinton, or Mitt Romney is really like as well.

Do not also forget Ronald Reagan. Probably would be considered a B level actor, A level radio commentator, and quite a celebrity. Celebrity Influences Political Votes - ABC News

I also would argue that Oprah's endorsement of Barack Obama pretty much made Obama into a huge political force in the US. Oprah Winfrey's endorsement of Barack Obama - Wikipedia, the free encyclopedia
