Guests - Seth Keshel, Jack Dona

Four days out from Arizona's primary, with the president's overnight address on election security still echoing, Kathleen Winn built her Friday broadcast around the one issue she and both of her guests treat as the foundation of everything else: whether the vote can be trusted. First a reminder for listeners caught off guard — last year's five mail-in elections left many assuming they were still on the early-ballot list when they were not. "You still can vote," Winn said. Go to a voting center today, or vote in person Tuesday. "We need your vote." From there she turned to two men who have spent years inside the mechanics of Arizona elections: a data analyst and Army veteran who forecasts vote trends, and a retired Master Sergeant who investigates election process.
