It must come down to the timeslot they are in. Brit Hume and Neil Cavuto are also my favorites on FoxNews. I actually like just about everyone who hosts a show or is a FoxNews contributor, even Alan Colmes. Alan is better than Paul Begala or James Carville any day.
For a liberal, Alan Colmes seems like an ok guy. Frankly, I'd rather watch Colmes than Sean Hannity, who's basically a sockpuppet for the RNC and seems to have little capacity for debate beyond a high-school level.
