Theory on 4-6% lost forever:

The 46th presidents term is lost forever. America and its interests will lose ground for the entirety of #46s time in office. Military will regress, GDP will decrease, jobs will flee, boarder fence will not be finished etc etc. Every facet of our country will either stay stagnant or diminish under 46 and those years will be lost forever all the while our adversaries will further their interests.
