What if GOP picks "None of the Above"?

So what if Mitt Romney loses Michigan, the place where he grew up, the place where his Dad was not just governor but a POPULAR governor who was thrust into politics after saving American Motors, the auto company that he once headed?

Well, you can take this part to the bank: Romney's people (if he loses) will play it down, his opponents will play it up.

But what will really matter is what we'll be hearing from other Republicans.

My prediction is you'll hear a chorus of voices calling on people like Jeb Bush, Indiana Governor Mitch Daniels, and the man we heard from earlier, Chris Christie, to rethink their decisions not to run, they'll be urged to get into the race.

Would they? Could they? I don't know about would they, but could they - and have a chance to win? The answer is yes. It's a long shot but they could.

There are 22 contests where the filing deadlines to get on the ballot in states are still open. Those states don't provide enough delegates for a late starter to get the nomination, BUT a late comer who got a big part of the delegates could probably stop any of the current candidates from wrapping up the nomination before the Republican convention.

Now this is a guess - clearly labeled - but if Republicans get to their convention with no nominee, I'll predict they'll pick someone other than those in the current field.

Why? Because if we've learned anything from this race, it is that Republicans have a red hot, burning fervor to beat Barack Obama - but it is a fervor they have not yet matched for any of their current candidates.

Who knows? We may be just getting started with all of this.
