Electeds are not beholden to anyone. They could actually do the right thing regardless of who sends in money. Corporate money isn't speech, despite what SCOTUS said in Citizens United, but citizens should maintain the right to donate to candidates who aren't in their district.
"Electeds are not beholden to anyone." They should be beholden to their constituents. That's the whole point of a representative government. Otherwise why do we bother having elections at all? The reality is they're beholden to the people who give them money so they can keep the job.
