He happens to be on the right side (Trump), but he's still not very bright.
I watched a recent video of him as a "late night" show guest -- I was disappointed, though I certainly gave him a chance.
It's fine though -- we need all kinds of supporters on the good side. Some will be good at creating videos, articulating themselves, etc. while others will just hold the line in their personal lives and show more humble forms of support -- even if that support is merely voting the right way.
Kanye -- because of his fame -- might get a few mainstream people to stop and think, but he's no intellectual who can argue and explain the issues concisely.
