The US is both a republic (a form of state in which the country is considered a "common good" and not the legal propriety of the sovereign) and a democracy (a system of governing in which all citizens have an equal say in the choices of government). (emphasis added)

House of Representatives representation at all. (No, nonvoting delegates don't count.)
The US is a republic of democratic states and territories. Not a democracy by iguana_tonante
's own definition. I don't see why this simple observation merits condescension.
