The Word That Keeps Coming To Mind Is Treason?

Since taking office 0bama's action and policies have been so opposed to the well being of the United States and the American People that the question is starting to be circulated, are 0bama's actions a perpetration of treason? His associations and appointments like his policies are also questionable, is it time for the Congress of the United States start considering charges of "Treason" and "Impeachment"? Your thoughts please?
