Maybe the problem is that the Constitution is a badly flawed document and trying to abide by its precepts is a path to failure. Consider that the Constitution affirmed a nation of laws and assigned the creation of those laws to Congress - not too surprising since it was essentially a congress which created the Constitution. The President is there granted the right and obligation to carry out those laws created by the Congress. Obama's weakness may be that he respects the Constitution too much and is committed to allowing Congress to play the strong hand granted to it. Certainly, the Bush presidency was an unConstitutional presidency - even a stolen one for that matter. It may be that the great irony surrounding this administration is that the President understands the Constitution while the public doesn't - because, if they did, then they (and even Green) would understand that Obama is playing his part exactly as envisioned by the Founding Fathers.
