The oath that Barack Obama will take on January 20, 2009, will require him to swear (or affirm) that he will preserve, protect, and defend the Constitution of the United States. Not a problem, he has already been doing that: He has said both publicly and privately to Iraqi leaders that the Bushist status of forces agreement was not binding without Congressional approval.
Salient quotes from the (formerly enforceable) Constitution:
All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives. (Article I, section 1)Sarah Palin thinks Obama puts ambition before country. As usual, she - and the Washington Times - are completely full of bullshit. Obama put America and its founding ideals first. The Bushists, not so much. They put power before country.
All Bills for raising Revenue shall originate in the House of Representatives; but the Senate may propose or concur with Amendments as on other Bills. (Article I, section 7)
[The President] shall have Power, by and with the Advice and Consent of the Senate, to make Treaties, provided two thirds of the Senators present concur. (Article II, section 2)
