I don't like or condone what Trump is doing here, but it's no different than the capitulation that's been going on with the GOP for nearly 20 years. After protesting, Ryan quickly reversed course and fell in line, and McConnell fell all over himself to give Nancy and Chuck what they wanted.
This after getting nothing done for nearly 8 months while telling us that Trump has no principles, but they took no opportunity to get something on his desk that he likely would have signed.
What Trump tried to do they resisted. The reason seemed to be that he was infantile, ADHD, had a grating personality, and wasn't diplomatic enough. Yet McConnell and Ryan didn't seem to be able at anytime to stand up and provide leadership to counter the supposed failings of Trump.
So I'm gonna pass this blame around to everyone in the GOP leadership in DC for this stagnant cesspool. I'll put some blame on Trump, but he shares it equally with everyone.
