I may not be able to come up with the perfect solution myself, but I'm sure there is a way to maintain regular people's ability to organize and even donate politically without having greedy corporate interests take over such entities. Politicians should work to find that solution and ban everything else.

There is just so much wrong with the U.S. electoral system, it's hard to even know where to start. Money in politics, the FPTP system (which also helped the pro-Brexit party in UK win the most seats again, despite the majority of votes going to anti-Brexit parties), electoral college, antiquated caucus system in primaries, all the technical obstacles that two parties have set against independents and third-parties to ensure they never have a real shot and that the real status-quo is maintained (permanent war, helping their wealthy friends, spying on everyone, keeping citizens in the dark about the real issues, etc).
