Now for the DJIA. Here's a chart showing its performance January 13, 1978 through January 5, 2018 with March 4, 2016 marked:
What it's showing is that the current general upward trend started well before 2016 election day. Like 8 months earlier. Again: This idea that any objective assessment looking at trends in the stock market over any meaningful period would suggest that something significant happened either in November 2016 or January 2017 to change things is absurd.
It's the same with other economic indicators. Trump took over when a number of positive trends were already in place. If you want to say he hasn't done anything to screw things up, fine. But he clearly didn't cause the positive trends that were already in place well before he got elected.
At the same time I'll admit that I'm amazed that the stock market has continued to rise. I thought people who bet on the future would be horrified by having a guy with a 0.50 BAC driving the car and wouldn't want to leave themselves exposed.
