Articles of impeachment is fine as this process stinks and I think this court failed, but we really, long-term, we need a constitutional amendment to make it clear that this is not okay.
I love the constitution, wonderful framework, but it needs the following amendments:
Anti-corruption measures on the judiciary (looking at you Thomas). Provide some teeth to enforce recusal and avoid conflicts of interest.
Term limits for justices and age limits on all elected/appointed officials at the highest level (justices, pres/VP, congress). Tie those to either the retirement age or a percentage of life expectancy (as we get older as a society, and work into our later years, federal officials should be able to remain longer too).
Divestment requirements for all federal elected and appointed officials. i.e. no more insider trading, sorry.
Replace the electoral college with a popular vote.
Replace the filibuster with nothing. Fuck that thing. Let the legislators legislate. If, whatever it is, is a bad idea, it'll be shown to be a bad idea and the next congress will fix it. This is especially important now that Chevron is no more. The court just replaced rules created by executive offices with the most dysfunctional branch of government (congress) without any prospect of undysfuctionalizing themselves.
Congress shouldn't be allowed to block supreme court justices without a vote. Once they are announced, they have X days to approve/deny or they are auto-approved.
(edit) I can't believe this has to be done, but the President is not above the law. The president must follow the law while in office, following "official acts" or not. This is a fucking democracy, not a dictatorship.
While I know there are other ways to approach a lot of these and those ways are easier is not the point of my post. These are things that the constitution is currently WRONG about and it should just be fixed.
