It seems to me that

if Mitt Romney carries the day next month, it is less because of his particular tactics this year and more a function of the fact that his rivals for the GOP nomination are a matchless collection of ass clowns and raving twits.
They have all had their two to six week stint as the "AntiMitt" du jour and each and every one of them have been undone by the same thing, a pronounced tendency to say whatever outrageous thing flits thru their tiny little heads all of it on the record going back a decade.
Shee-it I could beat this rabble and I'm a democrat.
Still, one thing this process has done, is that it has inexorably, and predicably, moved Mitt Romney to right just as it did in 2008.  Count on it, a  few right hooks to that glass chin of his and Mitt turns into Bourke Hickenlooper every time. Why, a mere six months ago, Mitt was running as the sensible moderate "The Grown Up" in this race and as of this weekend he has come out as a slayer of social security and a libertarian "simplifier" of gummint.
Likely though, if Romney loses next month, he'll drop this android campaign plan and simply go berserk like he did in Michigan in 2008.

The one thing on which you can rely with Mitt Romney is that he remains a hopeless amateur...
