However, the Supreme Court has been able to gain a significant amount of power over the last 40 yrs, actually making rulings become laws (essentially)... Well for that matter, all branches have taken a lot of power they shouldn't have. Most recently I'd say, the Executive branch has the most with the Patriot Act, secret courts etc etc, basically anything that involves national security, is subject to w/e... If I were to say, who has the most power, I'd say the President, since he is in control of the military; unlike congress. Congress can only remove the president through impeachment (2/3s of both bodies must agree), if that is if I am remembering the specific gov't details; and/or if the Cabnit says to remove him due to duress. anywho... if anyone wants to quote specific sources that says otherwise, im gonna stay w/ that .. have fun edit: Cons!@#$%^&*ution -- Article 2... "Section 4. The President, Vice President and all civil officers of the United States, shall be removed from office on impeachment for, and conviction of, treason, bribery, or other high crimes and misdemeanors.
