I think Newt would have been well advised to quit saying “Callista and I...”
Let us not forget that Romney scraped a MI win by only 3% and Gingrich siphoned off 7% of the vote. Had Gingrich quit, Romney would have lost in MI and his campaign would have been reduced to ashes. Romney won OH by under 1% where Gingrich diverted 14% of the vote. In both instances he got zero delegates but helped Romney win these crucial states, secure the momentum, that went on to win against a cash-strapped Santorum. Now he expects Santorum delegates and supporters to cross over to him!
