We know that a boa conscriptor doesn't kill its prey through crushing. When the captive breathes out, the snake tightens its grip so the victim can't breathe in again. It suffocates its prey.

Voting for Biden is like embracing a boa conscriptor rather than a rattle snake. Yes Trump is a rattler but you probably have a better chance of survival so long as you can get hold of the antidote.

Biden is worse, not because he is a worse person or his policies are worse (though both might be true), because he embodies everything that is wrong with the US. He is more toxic than Trump even if he is less immediately or obviously dangerous.
