I know that it's popular to dismiss President Biden. I get it. He's old. This is the first election featuring the 2 oldest candidates, ever.
So what?
The future of the WORLD is literally dependent on this election.
To boot Biden from the ticket and try to bootstrap another candidate is madness. Booting this incumbent and hoping his VP will succeed is like firing the cook and hoping the dishwasher will give you Michelin-quality food.
Stick with the old man, and figure out a way to enact his popular policies while also expanding the Supreme Court, enacting term limits and limiting "Christian" Nationalists.
All this is just 'it shoulda been Bernie' without even specifying a Bernie. It's letting perfect be the enemy of good, with the limpest hand-wave toward what would be better.
Meanwhile, the alternative to the lesser evil is outright fascism.
You should generally stop fascists from taking power.
If you want to do more than vote, go right the fuck ahead.
If you want to do less than vote, shut the fuck up.
This is literally the least you can do. It's not complicated. Choose less evil.
