Coming off of Florida, John McCain had the wind in his sails. Had Super Tuesday been Super Thursday ... or Super Saturday ... McCain would probably have done even better than he did last night.
On the other hand, it is clear that voters who decided late, broke for Romney. (One possible reason for this is that Rush Limbaugh's attacks started to resonate.)
My guess is that if Mitt Romney had a few more days, it's very possible that he would have done better last night.
This morning, Mitt Romney may be thinking of Vince Lombardi's famous quote: "We didn't lose, we just ran out of time."
