Wrong again, Bubba. Great Britain, Northern Ireland, Israel, and New Zealand are all Democracies, yet they have no codified constitution. Therefore they have no protection under First and Second Amendment rights. The ancient Greeks invented Democracy, but their crude constitution offered very little in the way of the rights of the individual. The US Constitution created the form of government we have in the US, which is a constitutional and federal republic.
A constitutional republic means that it is one in which, rather than directly governing, the people select some of their members to temporarily serve in political office; the constitutional part means that both the citizens and their governing officials are bound to follow the rules established in that Constitution. A federal republic is one in which a federal government is given only limited powers for limited purposes, while state governments retain most powers of government.
