I'm no fan of Trump.
I'm no fan of Biden.
I'm not sure I even like democracy anymore, but banning him from running seems like a bad idea when the guy you banned, and his followers, believe the last election was rigged.
It's the wrong solution to the problem. As much as these fools talk about "crypto" these days, you would think they might learn cryptography is used to verify software integrity. We should have a way to verify vote integrity the same way we verify the Sparrow Wallet. You don't need a thirsty, ocean-boiling, blockchain either.
