James Madison was not a democrat. He denounced popular rule as "incompatible with personal security or the rights of property." Democracy, he observed, must be confined to a "small spot" (like Athens). Indeed, the Bush administration's deafening demagoguery notwithstanding, democratic majoritarianism is thoroughly un-American.
Madison and the other Founders attempted to forestall democracy by devising a republic, the hallmark of which was the preservation of individual liberty. To that end, they restricted the federal government to a handful of enumerated powers. Decentralization, devolution of authority, and the restrictions on government imposed by a Bill of Rights were to ensure that few issues were left to the adjudication of a national majority.
