The lesson here, of course, is that Romney is way ahead in collecting insider endorsements. And endorsements, as we know, do a much better job predicting who will get the nomination than money, polls, or anything else.
Okay, now the second graph (via Mark Blumenthal), which provides vital context for the first:
That said, it's hard to say just what exactly the insiders are waiting for. The field is set. Several potentially good candidates have decided to sit this one out. So insiders can go with Romney or they can pick from the others who we saw on stage this week at the debate, and that pretty much means Perry. And we already know about as much about Perry as we're going to know. He's a lousy debater and he's probably going to stay that way. He's a bit off the party message on immigration and vaccinations but is otherwise pretty reliably conservative. Meanwhile, the economy will probably continue grow at a weak pace but probably not go back into a recession, leaving Obama vulnerable but not automatically toast. The information just won't get much better than that. What more do they want to know?
