As Davis recognized in the 1970s, forcing the two national parties to compete for black votes would not allow any one party to take the constituency for granted. Indeed, even though the DNC wants to profit from a West fundraiser, the Obama White House has also prohibited Mr. West from giving the president any political advice at the event, an attitude reflecting Mr. Obama's general distancing from the hip-hop community. Furthermore, Ms. Clinton and Democratic challenger Bernie Sanders have not given much lip service to racial issues at their campaign stops. Such competition would benefit African Americans in terms of policy but also give them more of a presence in the White House, no matter which party was in power. Mr. West's interest in Dr. Carson should signal the Republican field that the GOP has the potential to reach African Americans, and that candidates should embrace opportunities to talk about issues that matter to black voters. It would be a shame for the Republicans, fielding the most riveting and diverse set of candidates in history, to miss this chance.
