The events that the Governor has laid out about his decision are quite clear. He had been thinking about running, and lots of people had been urging him to run. The decision was made when he and his wife were talking about the state of the Nation and she said it was time for him to get out of his comfort zone and make a difference.
If you are going to bring in wives, I think you should contrast Anita Perry with a couple of other wives of candidates: one who votes and says she’s a Democrat, another who, (worse,in my opinion) slept with a married man and who, rumor has it, required a bribe to go along with her husband’s race.
As for the 'unnamed'; don't hold much to rumors. As for sleeping with a married man; yep; it happens; they did make it legal, however; and there were no children and so family to impact. And, who knows; perhaps, no real marriage to break up.
Personally, do not care about Newt's personal past. (He has settled down; and has found a religion to call his own.) OTOH; do desperately care, about America's future; and want the 'best minds' on the job; speaking authentically and acting on America's behalf.
Sorry, but I think of Perry as a man who 'approves of this message' rather than writing it; himself.
