I’m thinking Newt Gingrich should be on that list. He has a lot to answer for with his bench warming with Pelosi and their AGW scam.
No, Gingrich most certainly did not support Obamao in 08 and he never stabbed Sarah Palin in the back.
In 08 Newt was urging the GOP to run a Nikolas Sarkoy style of Campaign, Reform from Within.
Appearing on a commercial for the Global Warming scam was poor judgment, but not an abandonment of Conservatism.
