Turns out God wants him on the floor, to borrow a line from “Hoosiers,” and also that our political system, which was peachy keen six months ago when he was cruising to the Republican nomination, is now “broken.” You know, Frum made a good point in his post backing Rubio: When Lieberman went indie after losing the 2006 primary to Lamont, at least there were important policy differences at stake. There’s nothing at stake here except ambition. Quoth Jeb Bush, “I am not surprised. This decision is not about policy or principles. It is about what he believes is in his political self-interest.” Try to force yourself to the end or else you’ll miss him insisting that the way to set a “new tone” in D.C. is to send another transparently careerist principle-less politician to Capitol Hill. Works for me.

The GOP onslaught has officially begun and Rove told Fox News this morning that he thinks it’s all downhill from here. Stand by for inevitable news stories announcing defections among his donors and campaign staff.
