Like I said, right or wrong....this will become a BIG issue and a losing one for Santorum if he wins the primary. He may win votes on this against Romney but surely will lose to Obama.
I don’t see any way Santorum loses to Obama. Santorum would put Florida, North Carolina, Virginia, Indiana, Iowa, Ohio, and Pennsylvania into the Republican column. And there isn’t a single state that McCain won four years ago that doesn’t go for Santorum as well.
