FILE - In this March 26, 2004 file photo, President George W. Bush waves as he boards Air Force One at Andrews Air Force Base, Md. President Barack Obama flies Air Force One when he leaves town. So does Candidate Barack Obama. The distinction between the two roles for Obama matters because it helps determine who foots the bill for his travel. Either way, though, it's a safe bet that taxpayers are on the hook for at least part of the tab. Operating under the same rules that have governed presidential travel dating back to the Reagan years, Obama must reimburse the government for a portion of the costs associated with any political travel. But presidents of both parties have been secretive about the complicated mechanics. (AP Photo/Gerald Herbert, File) less
