while i find chris matthews objectionable from time to time, he really is the only weekday host that's bearable, and not completely biased. he really likes edwards as a person and a candidate, and lets it show. since he doesn't stroke the administration's nuts, he'd never work on cnn or faux news channel.
keith olbermann is good, but he rarely ever interviews anybody, and still covers too much entertainment (i.e. britney and k-fed) garbage, even if he is making fun of them.
the only good interviewers out there are matthews and stephanopolous on sundays. although nobody asks tougher questions than jon stewart. seriously...
