“After being found guilty on seven felony counts, I had hoped Senator Stevens would take the opportunity to do the statesman-like thing and erase the cloud that is covering his Senate seat,” Ms. Palin said in a statement released by the campaign. “He has not done so. Alaskans are grateful for his decades of public service, but the time has come for him to step aside.”

Ms. Palin also made a direct reference to the hope that Republicans in Alaska are clinging to and is being chatted up on talk radio here.

“Even if elected on Tuesday,” she said, “Senator Stevens should step aside to allow a special election to give Alaskans a real choice of who will serve them in Congress.”

With just a week before Election Day, it is too late to add or remove names from the ballot.

“If there’s going to be any opportunity for people to vote for a conservative candidate in the future, people have to vote for Stevens now,” Mr. Pierre said. “Otherwise we have Mark Begich. We want folks to remember that Alaska can’t afford to have a Democratic supermajority in the Senate.”

Of course, Mr. Stevens, 84, would also have to resign for there to be a special election. He could possibly do so if he loses his appeals in court or if he is threatened with a vote of expulsion by the Senate.

Yet Mr. Stevens, a 40-year incumbent and long the state’s most powerful politician, has said he has no intention of resigning, now or in the future. The senator plans to return to Alaska to campaign on Wednesday, and he has signaled that he will try to tap into many Alaskans’ distrust for the federal government by arguing that his conviction in Washington on Monday was flawed and came from a biased jury in a liberal city.
