As much as I love Bill Clinton, the President gets more credit (and blame) for the economy than he (or she) deserves. At the minimum without buy-in from congress it’s tough to do anything. On top of that, 90-95% of the economy and jobs is controlled by forces beyond government control.
The biggest area it can be controlled is short term jobs created by infrastructure projects. If Trump does bring those jobs back it would be in very un-Republican, fiscal conservative fashion, as they are very Big Government.
