Well there are other choices besides Romney and Perry..and if Palin runs even more then. who knows Trump may determine to step in again for all wwe know!
At this point Newt looks good as well despite his personal life and "other" questionable behavior. He loves our country and would certainly mop Obama all over the floor in any debate. But I have to look closer at how he sees immigration issues.
Interesting that you mentioned Trump.....
He was the only (now former) candidate who said he would put troops on the U.S. / Mexican border.
Would he actually do it if he was still a candidate, won the nomination, and was elected President? Who knows. But I like the idea.
