DALLAS — When reporters arrived at Hillary Clinton’s campaign plane, someone was missing — the candidate.

Officials for the campaign refused to say where Clinton was or why she was not making the flight to Ohio this evening. With the plane en route from Love Field, Clinton had no public events scheduled tonight in Ohio.

Clinton’s mystery disappearing act came, ironically, on a day where she had criticized her rival, Barack Obama, for being “missing in action” on critical issues involving foreign affairs.Aides said there was no health problem with Clinton. Her Secret Service detail also was not on the flight from Dallas.

Clinton aides also refused to say if she was traveling to North Carolina, the home of former presidential candidate John Edwards. Both Clinton and Obama have actively courted the former senator's endorsement.
