Nope.
First, you are saying they cant uphold the constitution and obey the senate rules they agreed to. HOGWASH. Since when is "acting like a mature adult" against defending the constitution? You can easily do both. I combed through the senate rules twice yesterday...couldnt find a single thing keeping anyone from upholding the constitution.
Second, more than anti-establishment, the people want less conflict and division. Congress' approval rating is so low because they "never can get anything done". And, like Reagan, Rand is putting himself in the place of being a statesman that can work with both sides. Being able to work with both sides is FAR better than trying to be anti-establishment.
The problem is the media and people. They think in extremes. You either need to be rude and call mitch a liar on the senate floor during debate OR you're sticking your nose in mitch's rear/cuddle buddy/etc. There is a HUGE gap here and Rand is in the middle of that where he should be. This is how Rand got a defund planned parenthood bill to the floor for a vote, and Cruz couldnt get a simple roll call vote to the floor...didnt even get 1 vote lol.
I'm hoping people wisen up, though I doubt it. Anti-establishment would just clog the drain more. We dont need a bigger clog. We need someone who is able, as Rand says, to persuade the other side and work with both. Its the smart place to be, and just because morons dont realize that, doesnt make it any less smart.
