Ok. Then I was confusing Summers with the guy who said he’d challenger her. I thought they were one and the same.
I didn’t know she didn’t endorse the republican but I’m not surprised. It may have just been tit for tat in her case but moderate republicans tend to be vengeful. Specter hated DeMint for endorsing Toomey. Chafee was glad the democrats won. Jeffords became an independent. Crist and Specter became democrats. Scozzafava endorsed the democrat. And on and on. That’s why these people need to be removed from power or be kept out of power. They are democrat handmaidens if not democrats in reality (Specter, Chafee, Crist and Scozzafava).
Collins votes against the GOP over half the time...that’s not “moderate”, that’s liberal. But, since the other rinos you listed are out of office, she will likely wind up the same way.
