"I'm very literate on policy... I've been involved with politics long before I was an actress, I just happen to have a platform now, I just happen to have a voice... I also care deeply about our country, so I find it irresponsible for people to go, 'She's an actress, what does she know?' That means, 'If you're a dentist, what do you know? If you're a lawyer, what do you know?' It's our profession, it's what we do, it's not who we are." Actress Eva Longoria defends the right of celebrities to get involved in U.S. politics. The former Desperate Housewives star has been campaigning for President Barack Obama's re-election.
