You had to figure that this was the next step. If you can't convince Congress anymore to give you the sort of powers and legislation you want, create them out of whole cloth through regulation.
Never mind that much of what the administration wants to pursue in a regulatory sense will inevitably be challenged in the courts or reversed by the next Republican in the White House (one hopes in 2012). But in the meantime, all hell is about to break loose.
This president has the arrogance and certitude of your average fifteen year old that what he wants to do is that what which must be done.
