So, Mitt Romney won enough last night to probably let him coast through to eventual nomination, barring some crazy turn of events.
Intrade has him at a 89% chance to win the nomination as of today (3/7/12):
I was sort of hoping Santorum would do better, because I think Obama could crush Santorum much easier in an election than Romney... but who knows.
One thing is for sure, though. They're all awful candidates.
