Biden, if elected, won't be President past the end of the first quarter. He will be replaced since they all know he is mentally unfit at this point in his life. Essentially, he is the placeholder until they take office, if that happens, and Harris can take over.
Outside of that, I like your sentiment here. A vote for either clown is a vote for slavery, loss of freedom, and a step towards Marxism.
The only difference is the speed.
