Constitutional democracy is the form of democracy in the United States.

The Republic of Iraq (which only really controls half of the land area of the country) is officially a constitutional democracy, but it is a relatively illiberal democracy. Iraqi Kurdistan is also a constitutional democracy and less illiberal. ISIL is an outright dictatorship and considers democracy to be Anti-Islamic.
