My anti-Romney stance is pretty well known here on FR, with literally 1,000’s of posts to back me up. And being from MA, I've seen Romney up close. All that being said, what Santorum said was both incorrect and disqualifies him from POTUS contention, IMO.
As far as supporting any Republican in November goes, I will not vote for Romney or Santorum, period. Obama will win this state going away.
I actually disagree with him, but I don’t see how you can condemn someone for holding a position that’s almost the same as yours.
Sure, you can say that not voting won’t affect the election. But why ever vote then, since your vote will never matter?
