That's why Kanye would lose in a landslide - Trump at least had a simple narrative he stuck to over the course of a campaign. Kanye can barely keep a narrative through a concert. Trump isn't the Republican equivalent of Kanye. Kanye is probably closer to the Republicans nominating Clint Eastwood in full-on chair-on-the-stage mode.
But that also begs the question how could he even win the primary in the first place then with such a sloppy campaign? (and just repeating "muh black vote" over and over doesn't answer it, elderly blacks, the type most likely to vote don't give a f[inks] about him, and the black vote is nowhere near enough on its own enough to win a Democratic primary especially with lily-white states opening the season, [how the f[inks] is
New Hampshire "tailor made" for him?], Millennials almost certainly would back Sanders or a Sanders-like candidate speaking to the issues they care about over him [can you imagine Kanye West introducing a coherent student loan debt plan?] and the type of liberal activists who go to caucuses won't back him. He has virtually no appeal to the non-black parts of Hillary and Obama's coalitions, and it's a stretch to assume he'd even get the black vote in those numbers.])
