It's interesting that passionate Biden supporters haven't tried to replace "Let's go, Brandon!" with "Let's go, Biden!"
It has the same cadence so there's nothing extra to to enunciate and takes the same amount of time to say and with the media behind it it could perfectly overwrite the Brandon chant. If you had enough people willing to chant it in public, that is.
And given the massive crowds that showed up to Joe's rallies it shouldn't be a problem to find that amount of people.
Real strange it hasn't happened.
