Anchorage Mayor Dan Sullivan easily secured the Republican nomination for Alaska lieutenant governor Tuesday night.

Shortly after midnight, Sullivan had more than 70 percent of the votes with 328 of 441 precincts reporting. Sullivan was up against Kelly Wolf, who ran as a Republican candidate for District 29 of the Alaska House of Representatives in 2012.

Current Lt. Gov. Mead Treadwell was seeking the Republican nomination for the U.S. Senate seat held by Sen. Mark Begich. Treadwell conceded late Tuesday night.

“I am pleased to be joining forces with the governor and his team,” Sullivan said in a prepared statement.

Sullivan will likely face Hollis French in the general election, who had more than 60 percent of the votes around midnight.
