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.

Article 1, Sec. 8 of the Constitution, which enumerates the power of Congress, states that "Congress shall have the Power To... establish an [sic] uniform Rule of Naturalization." Congress has passed numerous laws pertaining to immigration and naturalization, including laws requiring the deportation of illegals.

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."

In theory, Obama could exercise his power in Article II, Sec 2. to "grant Reprieves and Pardons for Offenses against the United States" and offer a blanket pardon for all violators of immigration law. He's not doing that, because he'd certainly lose in November if he did. (However we should be concerned that if he does lose in November, he'll do it anyway on his last day in office).

The upshot of Obama's policy not only to allow hundreds of thousands of illegals to live and work in the U.S. during a time of 8 to 10% unemployment, but even worse, since the vast number of illegals we're talking about are Hispanics eligible for affirmative-action preferences, to actually get preferential treatment over native-born Americans.

Remember Obama's speech in Berlin in 2008? Well, now you know what "citizen of the world" means: instituting an illegal and unconstitutional policy that favors Third Worlders, and disadvantages people actually born as U.S. citizens.

Of course, he'll get away with it... if you think the gutless Republicans in the House actually represent the interests of their native born constituents and will introduce articles of impeachment, I have a bridge in Brooklyn to sell you....
