President Obama campaigned for Hillary Clinton in Pennsylvania on Tuesday, as the Democratic presidential nominee stayed off the trail for a second straight day to recuperate from pneumonia. Obama said Clinton was the most qualified person ever to run for the presidency, having traveled to more countries than any other secretary of state. He said her rival, Republican nominee Donald Trump, is not qualified “in any way, shape, or form” to be commander in chief. “This is not me just going through the motions here,” Obama said. “I really, really, really want to elect Hillary Clinton.” Clinton plans to return to the campaign trail on Thursday, aides said.
