Not anymore we don't, or havn't you noticed? The President wants to bypass congress with "Fast Track" trade abilities, very dangerous idea, and denial of Justice Department documents for Congressional oversight. And as for Congress itself, it can't be trusted with anything anymore period, it's members blab national security secrets, the height of an example of their corruption is to pass laws without even reading them, and so does the Senate. And the Senate Majority leader is trying to overthrow the Constitution by denying the Senate the ability to pass a bill with a majority vote.
The President won't President, the Congress won't Congress, the Senate won't Senate, and the Supreme Court cuts off the citizens right to have them address grievances by refusing to hear any case that overthrows an unconstitutional law they want kept on the books. The INS won't do it's job, the F.B.I. and B.A.T.F. are dangerous jokes, the E.P.A. is an arm of the United Nations, nothing in government is working as intended.
Gee, it is such a shame that MissAmericanPie's version of constitutional government is not implemented well known channeler of the founding fathers such as she is.
