Here's my 2 cents, take it or leave it.

A person does not give up their citizenship or their right to free expression just because they become famous.
If I had a talk show on tv, or I was walking down the red carpet and was asked who I was supporting, I wouldn't hesitate. As it is, I talk to friends and co workers about my politics, to try and change minds.
Millions and millions of voters do not have a degree, nor do they research the candidates. Is that encouraging? No. But they may have a single issue that drives them to the polls. Celebrities have the same right to vote on the issue(s) that are most important to them, and they have the right to avail themselves of any opprtunity to speak their mind on such issues.

That being said, I have never voted a certain way just because of a celebrity.
