The challenge for the media and Republicans is that they keep wanting to look at things through liberal vs conservative issues, social and otherwise. Trump threw that out and it is now American First, nationalism, etc. Those are distinctly color, race, and ethnic blind. Further, he is an alpha-male and swept the floor of the other Republicans. His little tirades have virtually insulated him on gender and so forth. Clinton’s woman card is neutered. The “she is a woman” meme is now almost pathetic. Who cares.
He stands alone with his America First theme which is even simpler than "Make America Great Again".
He has rewritten a new chapter in the book on political campaigning, though it's hard to conceive of someone following in his footsteps who doesn't have his unique experience in big city real estate, TV celebrity, and flair for communicating with people on a personal level.
