To the extent that they succeed, the public will have less access to both sides of issues. What is most corrupting, as campaign finance reformers see it, are political contributions from private businesses. But most big businesses contribute to both the Democrats and the Republicans. Much of this is protection money, to stay on the good side of whoever wins the election and thereby acquires the power to harass them with bureaucrats, red tape and lawsuits. But campaign finance reformers constantly depict it as bribes to win special favors.
Some businesses do win special favors.
But businesses as a whole are losing more and more rights to run their own businesses, while government agencies are increasingly telling them who they can hire, what they have to pay and a thousand other details that were once considered none of the government's business. If business contributions are primarily bribes, they are certainly not getting what they paid for. But protection money is paid to try to keep things from getting much worse. In the media, much was made of the many millions of dollars in campaign contributions received by George W. Bush. What was seldom reported was that the bulk of those millions came in small contributions from people too numerous to even have their names remembered, much less wield any influence over his decisions.
