This has been a consistent thing for like a decade now though. It's super clear that the Russians have been obviously influencing all manner of conservative governments across the planet.
Just take money out of politics entirely. Nobody should have PACS or donations or anything. You campaign on your ideals and not on flashy advertisements.
Campaign donations limits should be linked to minimum wage. Something like 2% of full time minimum wage salary after taxes. This would make influence over political parties more democratic.
Also limit donations to eligible voters, to party's/candidates that they can vote for.
