The president's executive order is an end-run around existing immigration law, as noted here:
If the citizens of this Republic still took the Constitution seriously, Obama would be impeached for his decision to unilaterally grant amnesty to certain illegal aliens. ...
The role of the President, according to Article II, Sec. 3, is to "take Care that the Laws be faithfully executed." Obama's refusal to execute Congress's immigration laws (or, for that matter, Congress's Defense of Marriage Act) is an impeachable offense. Article II, Sec. 4 states that the President "shall be removed from Office on Impeachment for... Treason, Bribery, or other High Crimes and Misdemeanors." The deliberate failure to enforce valid immigration law and allow hordes of foreigners to live and work in the U.S. is, arguably, "treason," and doing so in an election year to appease Hispanic voters could certainly be considered "bribery."
