Polls opened at 7 a.m. Tuesday for Alaska’s primary election, and voters can cast a ballot at several locations throughout Mountain View.

The neighborhood is part of District 19, which includes six precincts and more than 9,000 registered voters. The vast majority of those voters are registered as undeclared, according to the Division of Elections. Democrats make up the second largest group of voters in the district.

Major decisions on Tuesday’s ballot include a referendum vote on Alaska’s new oil tax measure, Senate Bill 21, and a tight race between Republican U.S. Senate candidates vying for the chance to challenge incumbent Democrat Sen. Mark Begich.

Poll workers say they’ve seen more voters than usual this primary election. More than 20 people had already cast ballots at Mountain View Elementary School as of 8:30 a.m., poll workers said. They said they expected to see the bulk of voters come through after 5 p.m.

Besides the elementary school, neighborhood voters can cast a ballot at the Mt. View Boys & Girls Club. Click here for a list of other polling locations throughout Anchorage; polls close at 8 p.m.
