and how that would work less than half a year before an election.
Normal countries don't have elections that last over half a year. It's clearly workable everywhere else, and it's not like the people already voting Biden are going to not vote for whoever the Dem candidate is.
I don't buy that it would cause confusion or somehow be less viable to change candidates; this isn't 1880, we have phones and TVs and the internet now. If the candidate changed as little as a month before the election everyone would still know what was going on, even if was a huge pain in the ass to account for in terms of ballots.
That would be funny as shit, but like basically everything Dark Brandon adjacent I fear it is more of a cope than reality.
