"Disappointed their conservative supporters" is a huge understatement. Anger, rage, hostility, and other terms might be more appropriate.
The reactions will include defections from the republican party and voting the 14 treasonous senators out of office. The picture that sticks in my mind are these traitors standing alongside the socialist subversive Chucky Schumer and the rest of the un-American democrats. Once again, jelly-spined republicans bent over to help Dear Leader with his agenda to destroy America.
