From the page: "Which brings us back to the voters of South Dakota. There's nothing inherently noble about a majority of people agreeing on a particular issue. Indeed, bad ideas often prove more popular than good ones. It's only when popular majorities are anchored to the idea of inalienable rights that they're most entitled to our respect. Without that underlying commitment to individualism, majority rule can and frequently will degenerate into the loss of liberty for unpopular minorities. The racist policies of the Jim Crow South, after all, were often extremely popular among white voters.
So before we get too misty over the will of the people of South Dakota, let's remember that James Madison warned us about the tyranny of the majority, not the tyranny of unfettered individual liberty."
