one thing for sure, the establishment is there for a reason. it's because the majority, over time, elected reps from both parties that supported the "status quo." now, people have spoken and rejected the status quo. backlash from the far left, and it's fair to say backlash from the right got the status quo relegated to the dust bin. or at least assigned to it, but not yet deposited in it.

if the establishment politicians are to be taught a lesson and sent home, it'll take a turn out of the voters who are disaffected by the establishment/status quo politicians and their policies. and that's when the fight started.
