"Mitt Romney approached him ultimately four times, using this private gathering as a political venture to further his image," Ellefsen told KIRO. "He kept introducing himself as Mitt Romney, a political figure. The same introduction, the same opening line ... [Doherty] said it was pathetic and comical to have the same person come up to you within only a half hour, have this person reintroduce himself to you, having absolutely no idea whatsoever that he just did this 20 minutes ago, and did not even recognize Glen's face."]
Even among Republicans, Romney is know as the guy that the more times you meet him, the less you like him. He claimed to be 'heart broken' after learning somebody he had met had been killed. It's pretty clear the only reason that he (or rather his staff) knew Willard had ever met this former Seal is from somebody else's recollection, or from facebook.
