Democrat John Lewis and Republican Ryan Zinke debated the nation's health care overhaul, immigration, limitations on federal power and other issues in their first debate.

The two U.S. House candidates were joined Saturday by Libertarian Mike Fellows, who says neither major-party candidate will work to limit government and suggests former National Security Agency contractor Edward Snowden should run for president.

Lewis says the health care overhaul has helped thousands of people but more can be done.

Zinke says the U.S. should "abandon ship" and come up with new solutions for affordable care.

Zinke's main message was that Americans are losing their trust in the government because of overreach and intrusion, but that it can be fixed.

Lewis says a paralyzed Congress has left unelected bureaucrats to make decisions that harm rural Americans.
