I don't really know what to think about the economic factors. Sometimes I'll read about how things are better now than they've been in 12-17 years. Unemployment is down, welfare is down, jobs are up, pay rates are up, the stock market is up, so there's no denying a lot of things are better today than they were two years ago. Then I'll read something else where someone takes a more critical look at those numbers, and points out all of the improvements have already been trending in those directions for eight years, and most of those trends haven't accelerated in the past two years, while the rate of some improvements have slightly decreased. But sure, things are better and if people want to give Trump credit for that, then it very well might get him re-elected.
A president's first couple years economic results are largely an effect of the prior administration. HOWEVER, any Republican tends
to get a bit of a bounce off of Wall Street's greater trust that their efforts won't be undermined. Strangely, given the effects of
conservative principles seen through the lens of the last 50 years or so, you'd think the opposite would be true - as deregulation
has led to the greatest economic catastrophes, but, no one said free market behavior was sensible.
