The majority does rule. But it is a rather special kind of majority. It consists of a coalition of special interest minorities. The way to get elected to Congress is to collect groups of, say, 2 or 3 percent of your constituents, each of which is strongly interested in one special issue that hardly concerns the rest of your constituents. Each group will be willing to vote for you if you promise to back its issue regardless of what you do about other issues. Put together enough such groups and you will have a 51 percent majority. That is the kind of logrolling majority that rules the country.
