From TPM Reader BS ...

How long after the election before John McCain shows "contrition" for how he campaigned?

Late Update: TPM Reader ST thinks we'll be waiting a long time ...

McCain will never apologize. This is his last shot, and he knows it. Maintaining his viability after embarrassing losses is what all of the previous apologies were for. Should he lose, he will no longer have any viability to protect, so he will switch to a shrill defense of his actions until the day he mercifully fades from the public eye.
