I've asked myself this question since November 2016. It is like a hydra, in that you cut off one head and another just as hateful takes its place. The comparisons to the rise of the Reich, and I'd argue, the rise of ISIS is similar to how the GOP keeps power. Manipulate the message or flat out lie, promote an extreme nationalist message that paints outsiders as criminals and the enemy, discredit or jail/kill critics, feed the greed machine that got you there. There are so many totems to topple. The disgusting behavior Trump shows is mirrored by those in the gop base. I think there will be a severe backlash against Trump in the next 2 election cycles. Hopefully that will help more states draw fair competitive districts, and end some of the extremism. Liberal ideas are popular. Push them, and don't be afraid of it. Yes, the right will kick and scream about changing, but it is only because they are afraid of change. Step up. That is why Bernie did well, and Alexandra Ocasio-Cortez won, and how others will win after them.
