In a well-kept neighborhood in Miami with lush gardens, Larry Smart, a county mosquito control inspector, holds a turkey baster up to the light. "If you look closely, you'll see some moving fast. They're wriggling around," he says. "That's actually mosquito larvae." Smart uses the turkey baster to sample standing water in hard-to-reach places.

Two and a half years before he killed 49 people in a June 12 shooting attack at Orlando's Pulse nightclub, Omar Mateen told investigators he'd been teased and verbally abused by co-workers for being Muslim. That abuse, he said, led him to claim ties to mass killers and terrorist groups, connections he later told the FBI he'd made up. The FBI concluded Mateen was not a threat.

As part of the project A Nation Engaged, NPR and member stations are going to political battlegrounds to ask people in key populations what they want from this presidential election.

With a population of more than 20 million, Florida is the country's largest swing state. And its population is changing — thanks to Puerto Rico.

Puerto Rico's stagnant economy has brought tens of thousands of Puerto Ricans to Florida each year over the last decade. Large numbers have settled in the area near Orlando.

The Triple S Mart in Baton Rouge has become a shrine and a gathering place for activists. It's where Alton Sterling was shot and killed by police officers just over a week ago.

Standing in front of a large mural of Sterling at the convenience store, his son, 15-year-old Cameron Sterling said he hoped his father's death would help bring people in the city together.

"My father was a good man," Cameron said. "That was a sacrifice to show everybody what was going on."

About a hundred miles north of Miami on the Atlantic Coast, the town of Stuart is a picturesque waterfront community — with homes, restaurants and parks overlooking the St. Lucie Estuary. But in many areas now, when you approach the water, the first thing you notice is the smell.

"There's no way to describe it," says John Skinner, a boat salesman in Stuart.

But he still tries. "I would say hundreds of dead animals that have been baking in the sun for weeks."
