Oscar winner Charlize Theron will be using her first vote as a U.S. citizen to support presidential hopeful Barack Obama. The South African-born actress recently became an American and admits she cannot wait to vote in a new American President. She tells WENN, "I looked at the candidates when I couldn't vote. I've lived in this country for a long time now and I feel very much at home here, so I definitely have an opinion and I'm definitely watching the race very closely. "I'm a huge Barack supporter. I like what this guy has to say. I know there's this whole question of his experience, but I think, when you look at all the great leaders that we've had, I'd go with the guy with the least experience but the one that actually wants to cause some real change. "I think there's something really inspiring and infectious about him. I think this guy's onto something. I like him."
