I've got to agree with that. It seems to me that Newt is all about getting himself the title "President of the United States".
He is not about advancing any conservative agenda. In fact, in that regard, Newt is like Romney - totally unpredictable. At least with Paul, Bachmann, and the rest you could comfortably predict what they would do.
Michelle Bachman is unknown in many areas ... stress situations, foreign affairs, defense, commitments, She is a nice person but how will she respond to pressure and attack? It will come if she rises in the polls.
