FAIRBANKS - Alaska voters went to the polls Tuesday to decide hotly contested races for governor and Alaska's U.S. Senate seat, as well as ballot measures that sought to legalize recreational marijuana, raise the minimum wage at limit certain types of mining in the state.

The race between Democrat Sen. Mark Begich and Republican Dan Sullivan drew national attention and millions of dollars from PACs. With three-fourths of the precincts reporting as of 10:55 p.m., Sullivan was in the lead, with 49 percent of the total, a lead of more than 11,000 votes. 

Incumbent Gov. Sean Parnell faced a strong challenge from independent candidate Bill Walker, who teamed up with Democrat Byron Mallott. As results came in, Walker took an early lead but Parnell drew closer as the night went on. With 73 percent of precincts reporting, Walker had a 1,690 vote lead.

Ballot Measure 2, which would legalize recreational marijuana in Alaska was ahead with 52 percent of the vote.

Ballot Measure Three seeks raise the minimum wage of $7.75 an hour by $2 an hour over two years and adjust it for inflation after that. Those in favor of raising the minimum wage took a strong lead, with 68 percent in favor.

Ballot Measure Four would require legislative approval for a large-scale metallic sulfide mining operation near Bristol Bay. This could have implications for the massive proposed gold-and-copper project known as the Pebble Mine. The measure was passing, with 65 percent saying yes.

Alaska's sole U.S. Congressman, Don Young, faced a challenge by Democrat Forrest Dunbar, who ran a buzzworthy, social media-centered campaign.
