This is the Madisonian scheme. Each institution shall be the jealous asserter of its prerogatives and try to maximize its power. I sometimes think that when he was at Harvard Law School, Mr. Obama cut class the day they got to the separation of powers, 'cause he seems to consider it not just an inconvenience but an indignity that although he got 270 electoral votes and therefore gets to be president, he didn't get everything. The Madisonian scheme is for the government to be hard to move. It's supposed to be. People look at Washington and say, oh gosh, this is so difficult. It's supposed to be difficult.
