Neither of the people elected have anything to do with running the country. Biden's too far gone and Kamala's too eager to do whatever she's told. If Biden wins this election, it won't be anything more or less than Obama's third term, because Obama never went away. The Founding Fathers set up an inordinate number of safeguards to prevent a "permanent ruler", and thanks to FDR it was locked down even tighter to prevent people from repeatedly running for office indefinitely, but there really isn't much in place to prevent a relatively small cabal of elites from just cycling through continuously, especially when almost none of them ever need to be voted for in the first place.
Again, I really need to stress that virtually every single member of Biden's proposed cabinet are people who worked for Obama's campaign in some respect, and I refuse to believe that's purely accidental, although I can't help but laugh at two things. One: Hillary hasn't been offered offered shit. Two: John Kerry is a remarkably hilarious pick for the "climate leader." Nothing like getting lectures from a man who owns 6 houses, 12 cars, a private jet and two yachts about how we all need to start riding bikes and eating bugs to save the environment.
The Founding Fathers anticipated tyrants and nobles, but I don't think they could have foreseen someone infecting the entire system. America's Republic is unnaturally robust, but it's only as strong as the voting class. If you ruin the voters' ability to perceive the truth and accurately measure who they're voting for, the entire system is practically useless. Obama was right about one thing, though: The U.S. Constitution is really just a piece of parchment. If you're not willing or able to defend or enforce what's written on it, it may as well just be an old dish rag.
