TAMPA, Fla. — On a wall full of guns is a sign that welcomes the presence of personal firearms in a cluttered pawn shop at the heart of this election battleground state. The invitation also extends to receptive ideas about climate change. Chris Fajardo, who handles sensitive deliveries for the store, answered easily when asked whether people are affecting the Earth's temperatures. "Yeah, absolutely," he said. Fajardo is the kind of voter Democratic presidential nominee Hillary Clinton is desperately trying to attract in the final days of the presidential race.
