"The sane wing ...

Of the GOP."

I'd posit to my friend Michael, that there's no such thing anymore, at least not amongst those who aspire to, or wish to retain, political office:

...

Back to Romney, though. He's evidently trying to capture the "sane" wing of the GOP, positioning his apparent sanity (non-Birther) against the insanity of so much of the rest of the party (including Trump and the Birthers). Will that get him anywhere? Not with his RomneyCare record, not with his flip-flopping over the years, and not with the general lack of credibility he has with the hardcore conservatives/extremists who make up the Republican grassroots and who, in a year without a leading establishment candidate (e.g., Dole, Bush II, McCain), will very likely determine the winner. (Pawlenty is trying to be the establishment candidate, but he has a lot to overcome, not least his lack of broad national appeal. The establishment, such as there is one anymore, is so desperate that the party could end up with an embarrassingly unelectable nominee like Sarah Palin or Michele Bachmann that draft-X campaigns are springing up around potential "sane" candidates like Mitch Daniels, Chris Christie, and Jeb Bush.)

...

Personally, I'd be more afraid of Romney appealing to supposedly "sane" Democrats if he won the nom, but there's too much loony in the Crazy Old Party for that to happen.
