Besides his moment on the couch with Nancy, I will never forget his COMPLETE FOLD in the debate just before the Florida Primary in 2012. Deer-in-the-headlights-Newt just stared at Mitt while Mitt savaged him on the question of whether Newt had peddled influence during his post-Congressional years in Washington.
I was a Newt supporter all through that campaign, and continued as one after Newts crushing defeat in Florida. But I will never forget my utter disappointment in the guy on the debate stage that evening.
