I work off an alternative hypothesis.
Trump’s the most recent and successful attempt by the ‘patriot movement’ people to gain a national stage for their crazy.
I think he made an observation about the possibility of riots. Cruz said there might be riots too. As did a few other important Republicans.
His support comes from a coalition of extreme right groups, as well as the rest of the electorate.
Most Trump supporters arent rabid psychos with guns. Many are however How many rabid psychos are required to make sure problems for the rest of us?
3 to 5% is what the rabid psychos say they need for a violent overthrow of the Federal government and to restore the Constitution as Jesus intended it to be. Or something.
The presidency is a popularity contest Trump cannot pass up. His campaign manager is the former Tea Party recruiter. They met about 5 years ago.
