Depends on definition of winning. If defined as “who did themselves the most good...”
1. Perry - Brought some game, fought with the front-runner, squeezed in all his talking points. This debate will keep the money spigot flowing.
2. Santorum - Made enough noise that somebody may begin to notice him.
3. Huntsman - Got a chance to work on his tan.
Perry did manage to ruffle “Mr.Cool-Slick’s” feathers. And it was a deserved pay-back. Romney looked like plastic, phony yes-man he has always been. He studies carefully what he thinks people want to hear. Perry exposed him like a wart on a frog's ass on that one and also demonstrated that when Romney gets exposed for what he is, he comes apart like a Singapore watch..
