FILE - In this Aug. 30, 2012 file photo, actor Clint Eastwood speaks to an empty chair while speaking to delegates at the Republican National Convention in Tampa, Fla. Campaign 2012 is rich with images that conjure the seriousness and silliness that unfold side-by-side in any presidential race. Sad to say, Eastwood's rambling conversation with an empty chair representing Obama during the GOP convention may well be the single most memorable moment of the 2012 presidential campaign. And the only candidate in that tableau was invisible. (AP Photo/Lynne Sladky, File)
