I think Charles was the right one to go. His voice is ok, but nothing special. And although I think there were worse performances last night, his have been consistently not-so-great.
I'm sort of rooting for Julia just because she's from my old hometown. I think we were in elementary school together at some point..

She won't win though; she sings well but she always seems uncomfortable onstage.
I also like Carmen. For someone that young (17) who had never even performed on a stage before this show, I think she's really good. She won't win either but I'd like to see her make it at least to like the top 5.
Ruben is obviously the best singer in the group. He has just never screwed up a single note. Same goes for Clay. The rest of them are alright but I think it would be almost impossible for both Ruben and Clay to lose.
