Though I do in no way feel certain about it, I really think you're seeing too much in Kanye West's candidacy. It could just as well be the death of such candidacies. Dan Bilzarian announced his candidacy 4 years ago, but wasn't on the ballot. Considering that few celebreties who are as narcissistic as Kanye, I'm not so sure that a candidacy that by all means won't go far will end up meaning that much. Sure it's a major blow for the democracy that we see such an unserious candidacy, but before he's on the ballot and actually get a decent number of votes, I personally don't see it as much more than what we've seen from the likes of Vermin Supreme.
We'll have to wait and see, but it honestly feels like he gets much more attention than he deserves.
