I don't think you can be 'establishment' at 22 unless you parents are serious big shots. Even then it would be hard. I mean, legally, you could only take a drink last year!
I am older, but have many younger friends who know I am wildly political and not in an establishment way. But I am very realistic too. Some might call it cynical, but I just don't expect much from politicians, in general. It is called 'politics' for a reason. It is POLITICAL. Consensus must be found in a democracy. That means compromise. Not hard to understand, IMO. Doesn't make me a shill or the establishment.
I am cold AF when I look at a politician. What can they realistically accomplish? How much can they be pressured on issues that matter to me? I don't have to fall in love. In fact, I TRY to keep it really business-like in my head. I felt guilty for liking Obama so much. It seemed like a total repudiation of my activist commitment. Politicians are there to be pressured. You don't LIKE them! If you do, they can use you instead, give you less than you earned through GOTV or protests. Not smart.
I respect Hillary Clinton. A bunch. She would have been a solid, smart, hard working, competent leader. Not sure why that wasn't enough. I find both Trump and Sanders to be loud and really high maintenance. Their policy positions are unrealistic. I didn't think either was open to outside pressure, either. They are both up in their own heads a bunch and don't listen to other POV or find consensus well. Oh well. It is what it is....
