Candidates in closely watched Senate race missing in action

CNN's Jeff Zeleny is in Pennsylvania where Democratic Lt. Gov. John Fetterman is slowly emerging from a near-fatal setback -- a stroke and heart condition that sent him to the hospital in May. Meanwhile, some Republicans are concerned that Dr. Mehmet Oz is not taking advantage of Fetterman's absence on the campaign trail. The two will face off in November in a race that could determine the balance of power in the US Senate. #CNN #News
