As of today, enough write-in ballots showing Lisa Murkowski's name have been counted, that she has passed Joe Miller in the Alaska Senate race.
Today's vote count is 92,164 votes for Murkowski compared to 90,458 votes for Miller. Murkowski's total includes 7,601 ballots which have been challenged by the Miller campaign -- the pending challenges will be heard after the count is complete.
However, if the remaining-to-be-counted ballots continue to be counted and challenged at the same rate that we've seen so far, Murkowski will have enough unchallenged votes to be declared the winner, rendering Miller's challenges moot.
