That's it, you're right, I'm going to vote for Mitt now!

Actually, no one ever votes for anyone.
A voter votes against candidates. No candidate ever shares all of a voter’s preferences so a voter has to compromise his principles every time he walks in a booth. Every time. No exceptions.
Hillary vs Romney. It is the only race in which Hillary can be stopped. The GOP has no money this year. The Dems have a fundraising machine running full blast. No other candidate can stop her, and he is rightward of her.
That’s pretty much it. Nothing more to examine or convolute. It is Hillary, or Obama vs the only Republican who can fund a campaign that can beat them. Get focused on the money realities because they decide the winner.
You have enough and compete, or you don’t and lose. In the case of the GOP this year, the situation is even worse than that. The Senate and House races where we have to fight a delaying action to limit seat losses (in a year where there are far far more GOP retirements than Dems) the GOP donor base has closed its pocketbooks. Any other candidate than Romney will have to draw down the GOP coffers to try to make payroll for the campaign. Romney can offset those demands with his checkbook.
These are the subtle realities of victory. You either let the Democrats achieve a veto override majority in Congress, rendering ANY GOP President irrelevant, or you fight tactically. Romney is the one with the brains. He can fight that tactical fight.
