Nope. Newt has too much baggage. Forget the personal issues. He supported health mandates, like Obama. He was on the couch with Pelosi...not good for the smartest man in the room. And, he took money from Fannie and Freddie. The Dems will hammer him on this.
Newt also started a for-profit organization called the Center for Health Transformation. What is it? Insurers and other health care industry players pay large membership fees and in return they, essentially, get to lobby Gingrich.
