Side note: I am reluctant to give any president undue credit for the economy.
In my opinion it is legislation that drives the economy.
A couple examples:
> Obama gets credit for the ACA (aka Obama Care). But the ACA is legislation and presidents don't draft legislation, Congress does. Yes, Obama signed it into law... but if there are aspects of the ACA that are bad, the fault lies with the H.R. & Senate.
> On the other hand Obama "fought" pretty hard to convince Congress to pass legislation that saved the U.S. auto industry, which was a huge factor in the growth of our economy. One example being trucks; U.S. trucks out sell foreign trucks massively >>> think jobs and money >>> a boost to the U.S. economy.
> Trump gets credit for the Tax reform bill of 2017. However, neither Trump nor anyone in the White House drafted that bill. Congress did. All Trump did was sign it.
> Trump acts like he bailed out the coal industry. That is likely not true, but even if it was true the impact on the U.S. economy is minimal (think not that many jobs nor money into the U.S. economy).
Now it is absolutely true and factual that presidents will push for certain aspects of important bills... dollar thresholds, milestones, and many particulars. None the less, it is Congress that drafts the bills (legislation) AND Congress can override a presidential veto. As such, it would make more sense for Republicans & Democrats in Congress to work together (compromise and cooperate) more... that way more could get done and if any given President tried to block Congress, a unified Congress could politically crush and president and essentially all but invalidate his/her administration.
HOWEVER >>> Americans, historically, have voted what is known as a "pocketbook" vote. That is, if the economy is good, don't change presidents. If the economy is bad, change presidents.
Thus, we can to a point expect Trump's re-election.
I admit to way over simplifying all of that
and there are other factors at play in U.S. politics right now.
