If you need proof that the Republican presidential candidates are an exceptionally weak field, you should read this Red State post about how a tepid former Romney supporter is becoming a tepid Gingrich supporter. Here's a bit:

What we’re left with in Romney is a clear picture of a man with no guiding principles beyond self interest. That is a recurring theme at Bain, as Massachusetts governor, and in now two runs for the presidency. He seems by all accounts to be a pleasant guy, unless you actually refuse to genuflect in his presence as Brett Baier discovered, and good family man. Of course, if you’re his dog, you better learn to like the view from the roof of his car.

I have a lot of doubts about Gingrich. He has a self destructive tendency. He has hubris by the truckload. He does not, in my estimation, build deep loyalty in his staff. Infidelity… While his changes in positions, to me, are mitigated by the fact that his bread and butter since 1998 has been in being quotable and provocative. This stands in contrast to Romney’s innumerable positions which were taken either while he was running for office or in the single instance in which he was actually elected to something. But still I do have concerns over what next great idea a President Gingrich may come up with. Different contexts and different causes for worry.

There's a lively discussion in the comment thread after the post. But again, nobody seems to be really up in arms over it. It's like they're trying to decide between two used Saabs.
