Unable to follow.   Indeed, blacks didn't show up for the Democrats, but that doesn't explain why so many whites of every income group, age, and gender voted FOR Trump.   Their system isn't ours - they could have remained staunch Republicans by voting R for their congressman that day and just left the President ballot blank.  And basically, the did not.
White Evangelicals voted for Mr. Two Corinthians; white women voted for Mr. Pussy-Grabber.   The ONLY common statistic is their skin colour.
