If due to a political miracle Donald J. Trump is elected the 45^th president of the United States, it is highly unlikely that he will fulfill his most prominent and visual campaign promise — the building of a wall along the U.S.-Mexico border.

Ironically, the barrier between Trump and his signature political project will be precisely what Trump continuously rails against — a bloated, ineffective, and inefficient U.S. government bureaucracy that (in Trump’s words) prevents our nation from “winning.”
