Of course many of those analyses include a portion of non-white voters but recent data points to two main factors in tRump's election: race and college education.

His "true believers" are the Republican base...the worst and dimmest rather than the best and brightest.

Bait and switch tactics on the gullible people he seeks out . He claimed he'd never touch Medicaid ,Medicare, and Social Security then signed into law with the GOPs help taking just under 2 trillion out of them, or that Mexico would pay for the wall, all bait and switch tactics often used by con men.
