Yep, and maybe a new term. “A Scozzafava” which is a party jumping RINO such as Arlin Spector and Jim Jeffords to name a couple.
Yes, and pronounced a little differently, "Scozzafavor", is what a RINO does for us when he/she shows her true RINO disdain for conservatism! Scozzafava just did us a huge Scozzafavor.
