Two things
1) It's a Supreme Court Justice, not a Supreme Judge (Not hating or anything, but would just like to clarify)
2) I'm pretty sure you're not against Citizen's United, but are actually against lobbying/corporate donors. Citizen's united did allow for campaign donations by corporations and other activist groups, but its main intent was to allow corporations/activist groups to make political media. If Citizen's United was overturned, you could say goodbye to things like political satire, opinionated talk shows/tv programs, etc. On the other hand, what you're describing is corporate donations / lobbying, which is really where you see the corrupt politicians.
Also, trying to legislate against Supreme Court decision (Recently exemplified by Oklahoma's anti-abortion law) would technically be unconstitutional, and would never become law.
I thought that everybody would at least know who I was talking about. Unfortunately, I'm not even close to 100% knowledgeable about all the different official terms and jargon. Glad at least you know who I was talking about, so I don't see not using the correct term as a loss on my part.
And yes, basically getting rid of Citizens United means that corporations and organizations will no longer be allowed to make
UNLIMITED POWER!!!! unlimited campaign finance contributions, which are pretty much bribes for their politicians of choice. Money isn't freedom of speech when you can outspend grassroots activists groups, metaphorically giving them a voice that is too loud to speak over.
And the loss of political satire, opinionated talk shows, and TV programs would be a small price to pay, which won't happen entirely, so long as the corporations, wealthy individuals, and coordinated groups for the wealthy fat pigs (refuse to call them the "wealthy elite", because I feel it gives them some validity) to pay for whatever laws they like, and block anything they don't. If anything, I expect them to use any victories to their advantage, and egg on supporters for the movement.
And so long as Citizens United is ruled as law, we'd have better luck starting over than trying to legislate laws banning unlimited and opaque campaign contributions, let alone make it an offense that is a jailable offense (which it should be, similar to the sentences that have been given out as a result of the war on drugs. It's fair to say that it is
a threat to destroying our democracy, if not at least 10 years in similar prisons. No country prisons for any assholes that continue to try to game the system).
But yes, the corporate, super PACs, and lobbying contributions needs to go. The ability to lobby should have nothing to do with money or the ability to do "favors".
