I’m rather surprised to hear he might endorse Newt. In one of the earlier debates, and afterwards, he opined, if you’d cheat on your wife you’d probably cheat on anybody else. Support of Newt would cause pundits and interviewers to dig that comment up time and again. Plus, I think he sincerely meant it.
Perry had improved considerably since the first stumble out of the gate, too bad that few people reconsidered!
Santorum otoh has NOT improved and ought to have the political sense that Perry is showing.
The reports are that he will endorse Newt, but until we hear it from Perry, I don’t count it as a done deal.
It would surprise me and disappoint me if Perry endorsed Romney or Santorum.
