Fact is Trump lost the popular vote by the largest margin in history for a winning president and his electoral college victory was fairly precarious, Michigan, Pennsylvania, and Wisconsin will likely be blue next time because they are historically blue states.
Clinton took them for granted and was a boring/dull candidate with a lot of baggage who didn't campaign enough. Both Sanders or Biden would've beaten Trump and held that blue wall.
