The law would work differently if they, as designated interpreters of the law, interpreted the law differently. If they said you can’t have infinite dark money running campaigns because that violates the rights of poor voters, then things would be very different. Plenty of SCOTUS cases have made significant changes to how the law is interpreted and enforced. Congress also seems to very rarely pass laws to counter SCOTUS decisions. So yeah, if we had fewer federalists and conservatives on SCOTUS and more progressives, I think it would have been decided differently, as well as other significant cases.

If money is free speech then anyone with more money gets more free speech, which isn’t how rights work. You have the same freedoms and limitations to those freedoms that I do, regardless of who has more money. We’re supposed to be equal under the law, but SCOTUS thinks $ome are more equal than others.
