Where are the Black Republicans?

Since Richard Nixon won about 30 percent of the Black vote in 1960, at a time when Black people were disenfranchised wholesale in the South, no Republican presidential candidate has been able to crack 15 percent (Gerald Ford in 1976) for the past half century. Donald Trump won as much as 12 percent of the Black vote in 2020, but he left the Republican Party facing accusations that it embraces racism and white supremacy after four divisive years in the White House. What has to happen to change that?
