I don’t think so Rockingham. Rubio stood before the American people and lied right to their faces. He now has zero credibility with the grassroots. I wouldn’t trust him for dog catcher. His credibility is shot, and he only has himself to blame.
I saw Nixon, McCain, and Romney get nominated for President after seemingly fatal political deceits and zig zags. I am not saying that Rubio will overcome his self-inflicted wounds, only that it is possible, even if unlikely.
