We ran off all the candidates early on.
You know that is something people don't see positively about Newt, Santorum or Paul, for that matter. How their supporters are just dug in, and won't let anybody run them off... if Gov Perry's supporters had done that, and prevailed upon him, he might still be here. Or any of the other candidates who opted out early on. As infuriating as it can sometimes be, there is something to be said for the people who dig in and don't desert their candidate, no matter what.
