Owe-bama/bush--patriot act, rendition, wireless taps?

gitmo, iraq, afghanistan. is there anything bush did that owe-bama has not fallen in line with. and do you think owe-bama saying gitmo would be closed in a year was his "mission accomplished" moment. why are they so much alike in security policies when owe-bama voted against all of these things but now he is their biggest supporter? thanks
