I'll consider Franken credible when he addresses Ted Kennedy and what happened at Chappaquiddick. Otherwise I'll continue to view his as a mouthy little pip-squeak who wouldn't get the time of day if liberals didn't control the mainstream media.
Al Franken looks like one of those guys who always got his ass kicked after school and now that somebody gives a sh!t what he has to say, he's making up for lost time. Wouldn't it be cool if we found out he was having an extra-marital affair with Arianna Huffington? After all, I hear she's partial to bi-sexual men.
OK, the smaller type thing is humorous. It's the same phenomenon we have seen umpteen million times on traditional (read: left-leaning) debate shows where you have some guy "from the Right!" (as Ann Coulter has pointed out)
