Quite possibly the reason Trump has so many angry white male supporters is because the white male democrats have all had enough of their party. Plenty to be angry with it about.
Trump won’t run third party. Remember, you heard it here.

Nor will he destroy the Repub party. It has never been a cohesive party and it isn’t destroyed yet.
Now, as a white male, I’m going to risk the racist brand and say the people who ought to be the angriest are black males. Their employment rate is terrible. Their children are the most likely to be aborted. They are the most affected negatively by illegal immigration, and Hispanic bias against them makes white bias against them look like a misunderstanding at a garden party. Their children are the targets of drugs and gangs. And, of course, the party that has run the country and which claims to be their friend has, for the last 7+ years only made their condition worse.
If Trump plays it right, he’ll get a lot more of them than anybody dreams right now. I don’t know if he’ll say the right things to them, but he should. The only differences between them and “angry white males” are their skin color, their worse condition, and realization how sorely they have been betrayed by the Dem party.
