You may be one of those people who believe there is too much money in politics. (Polling suggests there are many such people—a vast majority of Americans, in fact.) You may believe that the larger the financial contribution, the greater the chance it will corrupt your representative in Congress, or even your president. You may believe that there are too many political advertisements on television, too many groups with blandly patriotic names trying to change your mind about energy or Medicare or national defense. You may even believe that the nation’s founders would be repelled by the idea of corporations and billionaires pouring millions of dollars into political campaigns. It is reasonable—it is quite respectable—to believe these things.
But if you are one of these people, what you believe is turning out not to matter very much.
