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."

It has been five years since NASA retired the space shuttle, ending a federal program that employed some 10,000 people around Cape Canaveral, Fla.

The loss of those jobs was a blow to Florida's Space Coast, an area closely identified with NASA and the nation's space program. But the region's economy is bouncing back and attracting companies that are in a new space race.

Miami Beach is one of the nation's cities most vulnerable to climate change — and its leaders are doing something about it. The city, a national leader in addressing climate, has begun to make improvements aimed at protecting residents from rising sea levels.

This election season establishment candidates have been put on the defensive. That's true in the Presidential campaign and in races further down on the ticket, including the re-election bid by the head of the Democratic National Committee, Congresswoman Debbie Wasserman Schultz.

Wasserman Shultz's challenger is drawing on national support and providing her with the first primary challenge of her career. So, who exactly is he?

He's Tim Canova, a stalwart progressive in the mold of Sanders himself.

Environmental activist Luis Jorge Rivera Herrera has worked to protect a pristine section of Puerto Rico's coastline. Now he's being honored with the Goldman Environmental Prize.

Millions of years of Florida's history are lying on a table in Paulette McFadden's office at the University of Florida in Gainesville. It's in long metal tubes containing several feet of sediment from Horseshoe Beach, a community on Florida's Gulf coast.

"This core," McFadden says, "actually spans about 30 million years."

Puerto Rico's governor has signed a bill that puts the island's debt payments on hold until January 2017. Gov. Alejandro Garcia Padilla says the island's first priority is covering payments for essential services.

Puerto Rico acted this week following reports that a key financial institution, the Government Development Bank, is nearly insolvent. A group of hedge funds went to court to block public agencies from withdrawing funds from the bank. Within hours, the Legislature moved to pass the debt moratorium by approving the measure.

In a major concession to critics and animal welfare groups, SeaWorld Parks & Entertainment Inc. says it will stop breeding captive killer whales.

SeaWorld's treatment of its killer whales, or orcas, was put in the spotlight three years ago by Blackfish, a documentary that examined the death of SeaWorld trainer Dawn Brancheau, who was killed by an orca named Tilikum. Since then, in a steady campaign on social media, critics have demanded SeaWorld end its orca breeding program.

Puerto Rico is losing people. Due to a decade-long recession, more than 50,000 residents leave the U.S. territory each year--most for jobs and new lives on the mainland. This issue is especially affecting healthcare, where it's estimated that at least one doctor leaves Puerto Rico every day.

SeaWorld says the health of one of its best-known killer whales is deteriorating. Tilikum is the orca that killed SeaWorld trainer Dawn Brancheau in 2010 — her death and SeaWorld's treatment of its killer whales were at the center of the documentary Blackfish.

San Jorge Children's Hospital is Puerto Rico's largest pediatric hospital, drawing patients from throughout the Caribbean. It's a bustling facility in San Juan, with specialties in surgery, rheumatology and oncology. It also has brightly colored live parrots at every entrance.

"It just sends a message to the patient that they're in a friendly place," explains San Jorge's vice president of operations, Domingo Cruz Vivaldi. "That they're here to be treated, but they're also going to have a good time."

The Zika virus is a health threat not just to Latin America, but also to parts of the U.S. It's already a problem in Puerto Rico where there are nearly 120 cases so far, including five pregnant women. That's a concern, because Zika may be involved in causing birth defects.

The Zika virus now has a foothold in a U.S. territory. Puerto Rico is reporting at least 117 Zika cases, including at least five pregnant women. That's of special concern because of Zika's possible link to birth defects.

In Bayamon, a San Juan suburb, Monica Figueroa is waiting in line at a lunch truck. She's a nurse who works at a nearby clinic and she is pregnant — "about five months and a few weeks, something like that," she says in Spanish. Figueroa knows about Zika. She says she's wearing mosquito repellent but is not especially worried.

When people talk about Florida's Everglades, they often use superlatives: It's the largest protected wilderness east of the Mississippi River, and it's the biggest subtropical wetland in North America.

But it is also the site of a joint federal-state plan that is the largest ecosystem restoration effort ever attempted — one that is beginning to pay off after decades of work.

Florida is one of several U.S. states now reporting a few isolated cases of people infected with the Zika virus. In response, Florida's Gov. Rick Scott has declared a public health emergency in five counties in hopes of getting ahead of the virus's spread.

So far, just 12 cases of the mosquito-borne illness have been reported to health authorities in Florida, all of them among travelers who contracted the disease outside the U.S. But Scott figures it's only a matter of time before the virus starts showing up among mosquitoes in some regions of the state, too.

Florida's highest court on Tuesday will hear a case that may determine the fate of some 390 people on the state's death row. Last month, the U.S. Supreme Court ruled Florida's system for imposing the death penalty is unconstitutional.

Florida has an execution set for next week. The state's highest court now must decide whether it can go forward.

The rapid spread of the Zika virus has raised interest in a British company that has developed a genetically modified mosquito. Oxitec has produced a genetically engineered line of the Aedes aegypti mosquito, the mosquito that carries dengue fever and chikungunya. Those tropical diseases have become common in Latin America and are now showing up in Florida.

Aedes aegypti also carries Zika, a disease whose symptoms include fever, like dengue. It has also been linked to a birth defect, microcephaly in children born to women infected with Zika.

Florida's Everglades is known for its alligators, and in recent years, pythons. Burmese pythons aren't native to the Everglades. But over the last two decades, the snakes, which can grow up to 20 feet, have become established there and taken a big toll on native wildlife.

With the pythons, there's another new Florida species — the python hunter. They've been featured on National Geographic and the Discovery Channel. And hunters are descending on the Everglades this month for a competition — the Python Challenge.

It won't be long until passengers will be able to take a ferry to Cuba from Miami, an idea that would have been unthinkable just a few years ago in a city that's home to Cuban exiles who fled from the Castro regime. The Obama administration approved licenses last year to companies that want to run ferries to Cuba. Several are interested. Still, it came as a surprise last week when the port of Miami said it's considering building a new ferry terminal on land that had been slated for development.

Hundreds of people were lined up when the gun show opened at the fairgrounds in Miami. It was mostly men, but there were quite a few women and even some kids. Winter is a busy time for gun sales in Florida. But this gun show was busier than usual.

Even before President Obama announced actions aimed at tightening controls on gun purchases, sales were up — partly in reaction to terrorist attacks in Paris and San Bernadino.

There was an unusual scene at Florida's Capitol building in Tallahassee this week. To comply with a court order, legislative staffers used a computer program to randomly assign new numbers to Florida's 40 state Senate districts.

It's the latest in a series of moves that have reshaped politics in the Sunshine State. The political ground shifted recently when the courts approved new maps for congressional districts and the state Senate. The maps are the result of laws that aim to eliminate gerrymandering: drawing districts to benefit one political party or another.

There's been a breakthrough in an impasse that's left several thousand Cuban migrants stranded in Central America.

In Latin American cultures, Christmas Eve is Noche Buena and time for a big family celebration, often featuring a pig roast. There are lots of ways to cook a whole pig. But at Noche Buena parties in South Florida and, increasingly, around the country, the preferred method for roasting a pig involves something known as a "China box."
