As meaningless an apples-and-oranges poll as CNN has ever coughed up, eight years of Bush with the books closed on it vs. Obama with at least two more years to finish screwing the pooch, plus Obama claiming credit for an Iraq close-out that was set before he was sworn in and the press unwilling to call him on it while he's still in office. Five or six years after Obama's last day in office, assuming he completes his term or terms (Shudder) normally, we'll actually have a real idea how they compare.
