Just after I recently proposed Al Franken as a worthy presidential contender it turns out he’s yet another sexual harasser on the run. Oh well, never mind. Give Franken credit for a quick admission, and the Democrats for vowing to do something about it in the Ethics Committee. But it took a credible charge to bring them out. And it is disappointing coming from someone who had done so much to shed his comic past in favor of being taken seriously as a substantive senator, and maybe more.
