It includes things like:
* Voters felt Trump was more genuine than Hillary. That's not hard to believe. Trump is raw and real to a fault. Hillary is a corrupt career politician.
* Make America prosperous again. Democrats like to ignore history that shows that conservative presidents bring far more prosperity; leftist presidents destroy prosperity.
* Trump was the best or only conservative option. In general, the best reason to vote for a candidate is simply that the other candidate is worse.
* A reaction to Obama. Thomas Sowell at the time believed Obama was the U.S. worst president ever. While not a historian myself, I am inclined to take the opinion seriously: https://www.youtube.com/watch?v=0UpiNiaak18&list=WL&index=1&...
And, if you are sick of the welfare tropes, you probably need more Sowell in your life: https://www.youtube.com/watch?v=rdwXoKTW3Ew
