Focus: Republican gubernatorial candidate Adam Laxalt

Who’s paying for it: Democratic gubernatorial candidate Steve Sisolak’s campaign

Size of buy: The campaign didn’t disclose this information.

When it started: Oct. 31

Where it’s running: The campaign didn’t disclose this information.

The gist: The 30-second ad released by Sisolak’s campaign attacks Laxalt, saying he will let insurance companies deny coverage for pre-existing conditions. It features a mother — identified as Shannon Barry — who says her daughter has cystic fibroris, a genetic condition that causes frequent lung infections and impairs the patient’s ability to breathe.

“We don’t want to go back to being terrified of losing insurance or not being able to provide care for our daughter,” Barry says in the ad. “Adam Laxalt is looking out for the insurance companies and not for Nevada families like ours.”

Laxalt, however, has promised to keep pre-existing condition protections in place despite being fiercely opposed to the federal Affordable Care Act.
