That totals in the neighborhood of 1100 delegates available so far.
That means roughly 1200 delegates remain to be won by some candidate.
No matter whose count you use, there are plenty of remaining delegates for Santorum to win this. He needs 59%.
Romney needs 41.6% to win.
Less than that will give a brokered convention, unless Santorum wins them at the above-mentioned 59% rate.
It would be hilarious if all the pro Romney manipulations ended up biting Mitt in the end.
It’s still within the realm of possibility.
