In 1980, Ronald Reagan won 56 percent of white voters and won a landslide victory of 44 states. In 2012, Mitt Romney won 59 percent of whites and lost with 24 states. But it’s a frequent talking point that white voter enthusiasm was higher for Reagan and turnout down for Romney. Not so. In 1980, 59 percent of whites voted and in 2012, 64 percent of whites voted.
But still the myth survives that there are these masses of untapped white voters just waiting for the right candidate. Call it the Lost Tribes of the Amazon theory: If only you paddle far enough up the river and bang the drum loud enough, these previously hidden voters will gather to the river’s edge. The simple truth is that there simply aren’t enough white voters in the America of 2016 to win a national election without also getting a substantial share of the non-white vote. Romney won 17 percent of the non-white vote. Depending on white voter turnout, a Republican needs between 25 percent and 35 percent of the non-white vote to win.

Among African Americans, 86 percent have an unfavorable view of Trump.
So let's play with that tool. Here's the 2012 numbers for Obama-Romney:
