I haven't watched or been keeping up here lately. Romney is going to get the nomination, so why bother?
I used to think that but the top-tier numbers are looking too morphic right now. We may well see a convention with no candidate with enough delegates to win out-right. Super Tuesday I, 6 Mar, will be the big tell on this question. Alaska, Georgia, Idaho, Massachusetts, North Dakota, Ohio, Oklahoma, Tennessee, Vermont, Virginia, and Wyoming will all hold Primaries on that day. Newt is bound to win several of those states; Romney is not going to run away with it in my opinion. And, I think, that Ron Paul is going to win some delegates that day too; he might even win Idaho and Vermont. Santorum is looking good in Ohio.
And next Tuesday is a big day for Romney; Michigan is almost a must-win for him; it's too close to call for anybody in the polling; that cannot be good for him. Arizona is the same day; I think he's going to win the McCain voters...and there's a lot of them there obviously.
Only time will tell I suppose.
