1. a bunch of nascar fans were chanting “fuck joe biden” at a car show
2. a reporter thought they were cheering “let’s go brandon” (one of the racecar drivers was named brandon)
3. right wingers start using “let’s go brandon” as a minced oath instead of saying “fuck joe biden”
4. left wingers start using “let’s go brandon” to signal support for joe biden. this turns into the dark brandon meme

Yes. American politics are that silly.
