LAS VEGAS | His conservative reputation wounded by the true-life soap opera of an extramarital affair and a betrayed best friend, Nevada Sen. John Ensign is trying to revive his political career and emerge victorious in a contest few think he can win.

Mr. Ensign, who faces ethics charges stemming from an affair with a former employee married to his longtime friend, has been touring Nevada asking constituents for their forgiveness as he prepares to run for a third term.

Once elected with a comfortable 55 percent of the vote, Mr. Ensign would typically face no real partisan opposition if not for the sex scandal clouding his prospects.

“It becomes something about trust and loyalty,” said Jennifer Duffy, a Cook Political Report senior analyst who has branded Mr. Ensign the nation’s most vulnerable incumbent. “It wasn’t like some one-night stand with a prostitute. It was the wife of his best friend.”

Mr. Ensign has nevertheless adopted a winsome front in public. When not in Congress, he has been zipping across Nevada since at least October, meeting with restaurateurs on the Las Vegas Strip, dishing with business owners in rural northern Nevada and touring a technology center in Reno, among other events that mostly focused on the Silver State’s deflated economy.

He seems eager to once again woo voters with his conservative principles. In recent weeks, he has pummeled President Obama’s health care law and rallied for a balanced federal budget.

Voters, as Mr. Ensign tells it, will prove more loyal than he was.

“It’s very encouraging,” Mr. Ensign, 52, told reporters in Washington recently. “They’re sticking with me.”

Among Mr. Ensign’s potential primary rivals are former state assemblywoman Sharron Angle and Rep. Dean Heller.

On the Democratic side, Rep. Shelley Berkley of Las Vegas, Secretary of State Ross Miller and Attorney General Catherine Cortez Masto are strong contenders.

In Nevada’s Republican-rich northern enclaves, voters are opaque about Mr. Ensign’s future.

“He’s been a fine senator,” said Michele Beard, of the Washoe County Republican Party. “But he’s made some really stupid personal decisions.”

Only a few years ago, Mr. Ensign’s potential political exile would have been unimaginable.

With his easy smile and unbuttoned elegance, Mr. Ensign was a polished foil to the Silver State’s other senator, Harry Reid.

Elected to the U.S. House in 1994, the former veterinarian preached family values, Christian fellowship and fiscal responsibility. He quickly blossomed from a little-known nice suit to the head of the National Republican Senatorial Committee after he was elected to the Senate in 2000. A 2009 trip to Iowa sparked speculation about a future presidential bid.
