In what future year can you see the GOP presidential ticket get more than 10%+ of the black vote?

Donald Trump got 8% of the black vote in 2016
George W. Bush got 11% of the black vote in 2004, and 9% in 2000
Ronald Reagan got 14% of the black vote in 1980 

The Republican Party has alienated black voters for at least a decade, despite making gains with black legislators, etc. Since Barack Obama transformed the Democratic Party electorally and demographically, the GOP has been seen as anti-black.
