Right now, the attack seems to be on the messenger rather than the message. The message is, the Ryan bill sucks. We can do a LOT better than that.
It seems like some of us are doing the same thing that democrats do - attacking the messenger. They go after Brietbart, they go after Rush, they go after anybody that speaks against them. Listen to what the conservative branch has to say, rather than demonizing them.
If you mean Trump saying he needs to work against the caucus I think that is less of an attack than a wake up call to them. It is akin to “be part of the solution not part of the problem”. “You will be held accountable if you don’t work with me to find a solution that we can pass that the American people will be well served by.”
