A good purging might be good. But it's the wrong zealots doing so, I think. And with the gerrymandering, there's very little longterm benefit. We just replace the powered people with a zealot. Kinda scary.
As an aside, the big one that I am worried about is climate change. A lot of the damage that Trump could do will be (for people on the outside) a shifting of our trade relations. Prices will go up, new suppliers found, and then a new normal will exist. I don't think supply side inflation helps anyone, but this is an instance where 'the free market' is going to do its job.
But climate change. Ugh. It's the biggest potential in being a giant race-to-the-bottom. Even if China continues its super-aggressive efforts for alt energy, the Trump protectionism will raise the price of the efforts. And really, what the point in holding back, to be reasonable, if one person at the party has decided to start scooping the communal appetizers into his tupperware?
