It’s an incomplete statement if you leave out the “why”. Lobbying. If that were regulated and corporation money didn’t indirectly buy votes through ad-spent but votes were won through actual policies and independent voter thinking, representatives would represent what voters (or a slice of them) wanted.

As it stands, they win elections by catering to a very, very small slice that can bring them into power: Corporations. Their donations are a more sure-fire bet to winning elections than trying to win over regular people.
