The insinuation that black people will cast their votes in an election for President of the United States, in favor of an entertainer with no credentials for the office, just because that entertainer is black, and "they simply love him and his music" is insulting to black voters. You would never imply that white people will cast their votes for President of the United States for Britney Spears - just because she is white, and "they simply love her and her music". Do you see how ridiculous this is, when you change the race of the entertainer to white instead of black, and suggest that white people will make a decision on a matter as serious as voting for President of the United States, based on such trivial criteria as "loving his/her music"?
The political objective of this campaign stunt is way too obvious. Blacks are smarter than you are giving them credit for. They can sense when they are being manipulated by a disingenuous ploy. It is insulting to their intelligence. Why not fight harder to appeal for the votes of black people by emphasizing the merits of Trump's presidency to them? Why does he want them to vote for a third party candidate? If his presidency has been as good for the black population as he insists it has been, then a stunt like this shouldn't be necessary.
Besides, West's name is being rejected in most jurisdictions anyway, for using fake names on petitions. That is called campaign fraud. New Jersey is one of the states that has rejected his petitions.
