The reason the SC stood up to the Administration is that they are immune from the Presidency and politics; they are on the Court for life, and there is little - short of a coup or outright assassination - that the President can do to overcome or eliminate the SC.
This is why Presidential elections matter; even in John McCain would have implemented every policy that Obama has, you can bet his SC nominee would be a LOT more conservative than Sotomayor!
Tell that to the Venezuelan Supreme Court.
What we have in the White House is a Dictator who will get what he wants, the law be dammed.
Its what happens when a Dictator has the "press and the people" on his side.
So far he hasn't even had to threaten the press all that much, just a little.
