When Republican Romney decried the ?prairie fire? of U.S. debt Tuesday, he ignored some of the sparks that set it ablaze. One was the Great Recession that took hold before Barack Obama became president. That landmark event went unmentioned in Romney?s speech. Another was a series of Bush-era tax cuts that Romney wants to follow with even lower rates. (AP Photo/Charlie Neibergall)
