JUNEAU, Alaska — Sen. Lisa Murkowski was officially named the winner of Alaska’s U.S. Senate race Thursday, following a legal battle that lasted longer than the write-in campaign she waged to keep her job.

Gov. Sean Parnell and Lt. Gov. Mead Treadwell signed the paperwork certifying her win in the hotly contested race.

“It’s done,” Treadwell said after penning his last signature in front of cameras in Parnell’s office.

The paperwork was expected to be hand-delivered to Washington, D.C., to guard against possible delays that could keep Murkowski from being sworn in with her colleagues on Wednesday.

Murkowski certified winner of Alaska Senate race

Sen. Lisa Murkowski was officially named the winner of Alaska’s U.S. Senate race Thursday, following a legal battle that lasted longer than the write-in campaign she waged to keep her job.

The official vote tally certified Thursday showed her margin of victory over her nearest opponent, Republican rival Joe Miller, was 10,252 votes.

“The voters have spoken. The courts have confirmed their voice,” Parnell said. “We have certified and attested to Sen. Murkowski’s election, and I would look forward to her being sworn in in the week ahead here.

Murkowski waged her longshot write-in bid after losing the August GOP primary to Miller, a Sarah Palin-backed tea party favorite making his first statewide run for public office.

She announced her write-in campaign Sept. 17 — an unprecedented effort in this state that lasted 46 days. Certification came 58 days after the election was held on November 2, 2010.
