This HAS been told before and it’s been discussed here on FR months ago. Many, including myself, predicted this would come up.
Marianne’s 2010 interview was about a lot more than cheating and a “sloppy personal life.” It painted a picture of a man who was maybe “not right” in the head. It also indicated that the Clintons know an awful lot about Newt that they haven’t let rip in public yet.
Their info, also, will come out, one way or the other, at a predictable time.
That’s what worries me too about a Newt candidacy. Newt made some enemies during his years in Congress, on both sides of the aisle. And their memories are long.
