Who is going to stop them?
I would hope even the liberal faction of the Supreme Court would toss out a bill not passed by both Houses, although sometimes one does wonder.
Really though, it would be about as obvious a constitutional violation as Reid declaring that a 45-55 vote against a bill was sufficient to pass it instead. If you’re willing to argue that he could get away with that too, then I guess all bets are off.
It IS scary to imagine what can happen when the President starts to ignore the law, as President Obama seems to do at will, while continuing to get away with it.
Wild guess, not us.
