If anything, he helped himself in 2012.
No, Mitt is done, as is Huckabee probably, for the presidency. Everyone associated with this farce of a nomination process will be written off as damaged goods.
Actually, Huckabee, by not endorsing McCain until the bitter end (wasn’t he supposed to do that so long ago and get the VP nod?) may give himself some credibility with his voters in 4 years.
Why, for endorsing McQueeg when conservatives are trying to drive a stake thru his heart?
