The great thing is that Trump has shown the Republicans the way to win going forward. The left in its rush to play identity politics and offer free stuff to free loading minorities have alienated the white majority in the country. Trump has figured out how to mobilize the whites to vote as bloc. That scares the Democrats to death. So they are desperately trying to bring Trump down in order to turn back the clock.
However even if due to Trump's stupidity they get him. The lessons of 2016 will live on and other more competenent leaders will arise and use the same strategy to fix America.
