Yeah I absolutely love the solution of requiring a supermajority. I wish it was required in most instances and that we actually required it when it is already required by the Constitution in practice. In the US Constitution it's only used to convict, override or expel people who were elected by simple majority (or in some case,s less, though I like the idea of the electoral college not giving all power to a couple of states), and for ratifying treaties and constitutional amendments. Of course, even though alcohol prohibition required a constitutional amendment, you can apparently prohibit anything else by having it "scheduled". And when was the last time the President waited for Congress's permission for our foreign relations, be they treaties or war?
