None, Trump didn't do the damage the backstabbing GOP establishment did the damage. They ran over 60,000 ads advocating conservative positions on the issues then after the election took a giant shit on conservatives, openly mocking them, bragging that they could win the White House without the conservative base. Trump is a product of the GOP establishment.

The "so called Conservative" platforms of the Tea Party, and Alt Right...are a huge turn off for anyone who isn't an uneducated white male over 50, who attends Church once a week.
The problem with Sarah Palin, Mitt Romney, and Donald Trump, is that the average voter DOES understand their agandas
