Kanye is brilliant.

How best to support Trump?

Declare your own candidacy, drag as many black and “allied” voters away from Biden as possible.

Well, OK, maybe he’s just a dumbass, since he’s bringing anti-vax and some BS about how he’s going to run the White House like (fictional) Wakanda.  Even so, any third-party candidacy that diverts votes from the Democrat sounds good to me.  My prediction is it won’t hurt Trump at all, because the black voters who have come over to Trump have done so because they perceive he’s actually helped them, and are unlikely to drop him for Krazy Kanye.

EDIT, 15 Jul 2020:  That was fast.  Kanye’s out.  LOL
