Akin and his fans think he can win despite this and that there won’t be any repercussions on other races. For Akin’s sake, they’d better be right. If this election goes bad because of this, forget mud, Akin’s reputation in the party will be about one step above guys like Mark Foley.
Whether he wins or not (and I don’t think he will - he posted a distorted poll, and a more objective one already shows him losing), he’s going to give the Dems something to harp on from now to the election. And in fact, by the time the election rolls around, even Missourians won’t vote for him. They may not vote for McCaskill, but they will essentially do so by not going to the polls if Akins is the candidate.
He should leave now, except that his giant ego is blocking the exits.
