"With Sean in the governor's seat, it won't be the politics of personal destruction, I don't believe," Palin said.

She added she wasn't sure what her next step would be.

"I can't predict the next fish run much less what's going to happen in a few years," she told the Daily News. "I don't know what I'm going to do. I'm going to keep working hard for Alaska."

Palin has spent the past four days with her family, but she returned to work as Alaska governor Tuesday in a remote fishing village 30 miles north of the Arctic Circle.

Palin was scheduled to appear in Kotzebue to sign a bill designed to bring public safety officers to small towns. Kotzebue, a town of about 3,000 people, is 550 miles northwest of Anchorage and lies on a spit of sand at the end of a peninsula.

There has been speculation that she has some legal issue that is not yet known to the public. But her lawyer told The Associated Press on Monday that she has no legal problems whatsoever, and simply is tired of the hostile political climate, legal bills and other distractions.

"She is leaving now because I think she believes that she has become the issue, rightly or wrongly, with all these ethics complaints and with the issues involving the Legislature, the combativeness they've been demonstrating toward her since she returned from the campaign," Thomas Van Flein said.

"I think she believes it's in the best interest of the state to progress forward, for her to move on to other issues."

Palin has become a lightning rod for partisan politics in Alaska since her return from the 2008 presidential campaign after John McCain selected her as his running mate for the GOP ticket. She has racked up an estimated $500,000 in legal bills defending the flurry of ethics complaints, including one filed Monday that alleges she is violating ethics law by taking per diem payments when she stays in her Wasilla home instead of the governor's mansion in Juneau.

In addition, her relationship with Democrats in the state Senate — once among her staunchest allies — deteriorated in the last session.

At the state Capitol in Juneau, the "Time to Make a Difference" clock that counted the time left in Palin's term was taken down from the wall outside her office. And people from around the country called up her office to inquire about the situation, as did a few cruise ship tourists who made the trek to the Capitol.

The young woman at the desk outside Palin's office was busy answering phones.

"Yes, she is getting swamped with e-mails," the woman tells one caller. "Yes, they do get forwarded to the appropriate person."

"Unfortunately, we are having a back load of e-mails so it will take some to get a response," she tells another.

Where is she? Why is she stepping down? When is her last day? Why so soon?

The tour guide tried to politely answer the questions for the tourists when she could, but for the most part had no answers.

Some of the visitors left Palin messages in a guest log.

"Sarah — Please Stay!" one person wrote.
