You really have to consider the audacity of this on multiple levels. For one thing, you don't need a congressional vote to establish the illegality of something that is already illegal. Obama knows perfectly well that executive amnesty was his decision to work outside the law because Congress wasn't on board with his agenda. It's one thing to complain that they won't do what you want. Every president has done that at some point. It's another thing entirely to decide that, because they wouldn't, you would.
