Damn the Constitution? He didn't do anything unConstitutional or even illegal. You really don't have a leg to stand on here.
Really?
The American people want immigration reform and the do nothing congress has consistently failed to do anything in that area. If the congress wants Obama's EO's on this matter to go away then all they have to do is get off their lazy asses and give the American people what they've been asking for for years.
This sentiment shreds the separation of powers, and spits on the very concept. The President doesn't get to act merely because he believes the Congress is acting too slowly for his liking.
