The Alaska Senate race is headed for another nail-biter in the rematch between Sen. Lisa Murkowski and tea party favorite Joe Miller.
The race is still undecided Thursday morning.
Write-in ballots hold the lead in the hotly contested three-person race, a potentially good sign for Murkowski's long-shot effort to keep her job.
With nearly 99 percent of precincts reporting, write-ins had 41 percent of the vote. Miller had 34 percent and Democrat Scott McAdams had about 24 percent. Write-ins had a 13,588-lead over Miller. Officials still need to count all write-in and absentee ballots.
Miller narrowly beat Murkowski in the Republican primary in August, prompting her to mount the write-in bid.
Murkowski expressed confidence at a rally that the campaign is close to victory, though it is expected to take at least two weeks before the race is decided.
