When Voldemort and Dumbledore are both off the chessboard, things should be fairly easy---Fudge is almost certainly on his way out at the Ministry, and I don't know of anybody there that'd be a real threat. Unlike Voldemort. I won't try to do too much at once. Step by step, and no more violence than is absolutely unavoidable---even Abbie Hoffman knew that much: "Random violence produces random political results. Why waste even a rock?" If Fudge can pick up tricks from the Communists, I can certainly learn from the Yippies.
