I wonder if what is going on is that Newt is difficult to work with, perhaps very difficult. The "insiders" know they're the ones who will end up having to work with a new Republican president; you and I won't be on the White House frequent visitors list.
I certainly agree with Noonan that Gingrich is a risky bet. I wish she'd agree with me that Romney is a boring bet. And I don't see Plan C on the horizon.
