"Incompetent" is a stretch. No chance of winning, perhaps, but that's only true because the two major parties continue to work together to make it true. Colluding with a fledgling fascist dictator to lock out other competition and then smirking about "wasted votes" maybe be stabard operating procedure but it shouldn't be.
Trump is a monster. Biden is not a good person. Let's kick then both to the curb and agree to support someone who isn't an objectively terrible person.
