Voters in a West Anchorage assembly race might be facing some bubble trouble. Starting Saturday, city officials will begin hand counting more than 7,000 votes cast in last Tuesday’s municipal election after concerns that some ovals marked correctly, according to municipal code, might not have been counted. At least that’s what the campaign of Nick Moe, the 26-year-old write-in candidate, is saying. Moe challenged incumbent Anchorage Assembly chairman Ernie Hall after Hall cut off testimony on a controversial ordinance designed to limit the power labor unions that do work for the city. On Monday, Moe’s campaign requested that Anchorage conduct a hand count of ballots in Assembly District 3, Seat D. That came after the city released a statement saying it would not perform a hand count unless the total number of write-in votes cast were equal to or more than the amount of votes for the leading candidate. The same release noted that there may be “other circumstances” where the votes would be hand-counted.
