Agreed that money should be virtually eliminated from the system. That said, people actually tend to be pretty satisfied with their representatives. It's the other Congresspeople who suck.
I bet you'll find that more people don't approve of what their representative is doing than do approve.
Low voter turnout allows for bullshit to slip through the cracks by targeting very small blocs of voters.
I genuinely believe that most problems in government would be fixed if voluntary voter turnout was around 99%, and that low rates, especially during midterms, is the largest threat to democracy in the United States as we know it to date.
