I disagree; the Presidents agenda and policies most certainly drive economic activity. During Obamaunism's malaise we kept hearing that we need to get used to 1.7% GDP and a lack of good paying jobs.
Now we are hearing Make America Great again and have a President reducing taxes, ending regulatory overkill, opening up territory to more drilling, eliminating unnecessary environmental restirictions and reducing Government payrolls.
I am sorry, but you are dead wrong thinking that a President cannot have a significant impact through his political saand policies.
Sean Hannity couldn't have put it any better, he would have especially liked working the "make America great" into it
