All "swing states" (maybe except for Ohio).
If Kanye gets on the ballot in those states, Trump will take them all.
Trump supporters won’t peel off for Kanye but Biden’s black vote is very soft (due to his political history) and a lot could head to Kanye. Why would they want a black woman as VP (controlled by a white guy) when they could have another black president, and a celebrity rapper at that?
Potus only won the rust-belt by small amounts. The union class and evangelicals who gave him a win won’t go to Kanye. Any black voter surge and maybe a youth surge will be absorbed by Kanye across the country. I can see the rust belts going again for Potus again, as well as the other swing states.
The danger here is the down-ballots. A surge of Kanye voters - will they vote Dem down-ballot? That would be bad as some astute people have commented earlier in this thread.
Too many twists in this story still to come.
