People hate political spending the same way that children hate spinach, but it turns out to be good to have. Studies show that spending increases voter knowledge and turnout, but it’s not cheap. One recent study showed it cost roughly $87 a vote to increase turnout. Unfortunately, current campaign-finance laws make it difficult for candidates to raise the money necessary to get their message to voters. Super PACs help fill that need. And that, in turn, means that candidates can spend less time fundraising and more time talking to voters.
