Boehner, McConnell, and Ryan are the reason why the GOP needs to be destroyed.
Many more than just those three, plus party "leaders" like Rinsed Prius.
I would add: Romney!
Even the best and brightest conservatives newly elected to office seem to emerge from a Washington DC orientation process which morphs them into nut-less, spineless, mush. This even applies to the USSC as in the case of Roberts.
Liberals by nature are group-think champions so their behavior is not at all surprising.
