While it is true the POTUS gets too much credit, or too much blame, for the economy, I think it matters to an extent. But, I disagree that Trump is the active element in the good economy. I think any Republican POTUS would see similar numbers. Indeed, I bet the economy would be modestly better if another GOPer were in there instead of Trump, be it Jeb(!), Lil' Marco, Krafty Kasich or Lyin' Ted. Why? They would not have started trade wars no one asked for that on the whole prevents growth in many manufacturing sectors because companies can't long-term plan for expansion due to volatility caused by these tariffs (among other large negatives in exchange for modest short-term gains). And the also the uncertainty that arose out of Trump declaring NAFTA is dead, or TPP is bad etc., etc.
