I'd like Ratigan a lot more if he didn't just come off as continuously bitchy all the time. In some ways, his personality is the kind that's the most annoying. His smug demeanor, with his "oh, BOTH sides are evil, I'm a REAL independent" bullshit. Then he has a republican corporate lacky appear on his show and lets them off easy (check out today's episode when he interviewed Tom Coburn for an example).
Maddow is much, much more skilled at eviscerating her opponents, while at the same time not coming off as whiny.
As for Ed Schult, I like the fact that he's a pretty amiable person, and he really does come off as sincere in wanting to help people, but holy shit does he suck at debating. He rarely gets a chance to properly rebut any republican's talking points, and if he can't do that effectively, he should change his show's format to resemble Olbermann's more closely.
