I would much have preferred Akin to quit, but he had a right to stay. Continuing to pile on is a stupid strategy. It was thinking like this that cost the Republicans Ted Stevens seat in Alaska after he was wrongly convicted (later overturned) just prior to the election.
The GOP is far more sensitive to scandal than the Rats are.
It ain’t easy being clean (or trying to be).
That said, I believe Akin did confess that he had been mistaken? If sincere, that ought to be the end of the brouhaha.
