Not hardly. People are still piling on, and the election is over.
After his ridiculously ignorant comment about rape (yes, it was), he never recovered from being double digits behind a looney leftist. There were others that could have beaten her, that polled way above her after Akin's idiotic remarks. He had time to drop out and give the nomination to good conservatives that could have won, but didn't.
If saying he lost it all by himself is piling on, so be it.
