That's false

In a democracy, whatever on earth the people vote for happens. They vote to send Jews to gas chambers or political opposition to gulags, it happens. In a Constitutional Federal Republic, sovereign and independent states rule their own affairs and can nullify any unconstitutional or abusive federal legislation. The federal government only has carefully enumerated and listed powers that the States delegated to it, and if the people vote for it to assume undelegated powers, screw how they voted. In a Constitutional Federal Republic, liberty is protected. In a democracy, the mob quickly swallows it up. The reason America is dying is because we have become far too democratic. We need more order, aristocracy, federalism, in our politics.
