Rick Perry's performance in last week's debate of GOP presidential candidates has been called a "train wreck," and "close to disqualifying" by fellow Republicans cool to Mitt Romney. GOP pundits, professionals and political donors are looking for somebody new, but after denying any interest, the Governor of New Jersey is now playing it coy. What did he say, and what didn't he say last night at the Reagan Library in California. If he did get in, who would he hurt most? Could he mount an effective campaign in time for next year's primaries? Can anybody unite the Republican Party?
