I've never heard them rightly rip into someone on "their side"
Uh, did it ever occur to you that they are more interested in the survival of the Republic, rather than giving succor to the electoral adversaries(democrats) who wish to dismantle the Republic.
Oh wait a minute, you only think about yourself, nevermind.
I have a lot more respect for people like John and Ken who will give hell equally to both sides when they deserve it, not just ass kissers who say nary a critical word about someone if they have an (R) after their name.
