Bill Kristol, on Fox News last night.
"I would be thinking about competing in Iowa. I do not think Romney can just sit back, let Perry muscle aside the other conservatives in Iowa.
I think what Romney will decide, I think this will happen, actually -- I've talked to some people pretty close to the campaign -- I think he will now compete in Iowa with Perry, if no one else gets into the race."
If so, a million stories comparing Romney 2012 to Hillary 2008 will be written, in addition to the million already written.
