Ms. Kirsten Powers.
She's smart, ready to back up her arguments, and doesn't opt for personal attacks when confronted with an opposing opinion. Her looks don't hurt much either. I'm even pretty sure that her smile in this latest Hot Air production is genuine and not a 'get me out of this room with these crazy conservatives' type of thing.
Judging by her article on Alaska's response to Hugo Chavez's gas offer, I think there's still hope that she may come into the light soon.
