To no one’s surprise, Mitch McConnell won handily tonight, a testament to his sure-footedness in Kentucky politics and to the folly of the groups that invested so much in defeating him. Those groups ran a weak candidate with probably only a long-shot chance to win at best and ended up, in effect, making a large in-kind contribution to the Alison Lundergan Grimes campaign — largely because they were bent on pursuing a vendetta with deep roots in the Senate cloakroom, consequences be damned. I’m glad that, as Pat notes, the groups are now endorsing McConnell, but this was a primary challenge that started out dumb and ended up dumber.
