So, show how I am wrong.
The same people who were looking under Bush finally got a break, Obama, as president, ordered the mission to go ahead, and Osama was captured. What more effort did Obama put into finding Osama?
Bush admitted that OsamaBinLaden (tm) wasn't a priority during his time in office. Do I have to Google it for you? Or are you one of those that clasps your hands to your ears and shouts "NA NA NA" when confronted with reality?
