I would go so far as to say that it’s vital that Biden handles court reform, because it has to be done before the election.
We can already be sure that Trump and his backers are planning legal challenges on whatever grounds might vaguely appear to be something resembling legitimate in the event that he loses, and we can also be sure that at least Thomas and Alito will rule in their favor, no matter how ludicrous their arguments might be, simply because they’re entirely and completely compromised. They’ve already demonstrated that law is irrelevant - that they serve demagoguery, shallow self-interest, bigotry and corruption. And given the chance, they WILL do their parts to destroy democracy in the US.
We can’t afford to give them the chance.
And that could be Biden’s legacy - the president who led the efforts that saved America from a fascist coup.
