Newt is carrying the buzz because he is smart enough, in this very complicated time, to sort it out and return fire to the enemy...Obama and the Left.
I like Perry, Cain (very much)...but Newt is the only one smart enough to go out on the battle field and meet Obama face to face.
Perry and Cain have stumble on their own feet. Perry in the debates and Cain on foreign affairs (and that blooper about "apples and oranges" with Romney a while back).
The problem here is that Newt will have to leave elephant in the room (obamacare) off limits. One person has completely shut down Newt in the debates, and it was Mitt Romney. Newt went on the attack regarding Mitt's role in Romneycare, and Mitt quickly brought up the fact that Newt supported the federal mandate to purchase anything, and Newt had absolutely no comeback to that.
Obama will do the exact same thing to him, and Obamacare is the biggest violation of the Constitution out there.
I like Perry and Cain too. I've even given money to Cain. But Perry will be portrayed as W 2.0. No way is he electable.
Cain would not defeat Obama in a debate. But with Newt, Obama would be reduced to a simpering puddle begging the moderator, "Mommy, please make the bad man stop."
