Like I've said before, Newt is a smart, sharp, sleazy politician. He might be the brainiest guy running for President right now, but he uses his wits for the wrong purpose. I believe this man has some deep-seated psychological issues to be honest... for those of you who know what my username/avatar are about, Newt strikes me as a character of Randian proportions... a kind of Ellsworth Toohey, if you will.
That said, if the Republican Party chooses him, he will win the Presidency. Obama doesn't stand a chance against a man of Newt's intellectual caliber.
