The Associated Press can project Alaska Sen. Lisa Murkowski will win re-election to the U.S. Senate, defeating challenger Kelly Tshibaka.
The Alaska Senate race pitted Murkowski against fellow Republican Tshibaka, who was endorsed by former President Trump, and Democrat Pat Chesbro due to the state's ranked choice voting system.
Moderate Republican Murkowski has served in the Senate since 2002, when she was appointed to the seat by her father, then Gov. Frank Murkowski.
The Alaska election on Nov. 8 employed a ranked choice election, in keeping with a 2020 voter initiative that implemented open primaries and ranked voting for general elections.
Under the ranked choice voting system, voters select in order of preference up to four candidates on the ballot. A candidate can win outright if they receive more than 50% of the vote in the first round, but if no one meets that threshold, the candidate with the fewest votes is eliminated and the second choice on those ballots is tallied. The rounds continue until a candidate has received over 50% support.
Murkowski was one of only a handful of Republicans to vote to impeach Trump for "incitement of insurrection" over the Jan. 6 riot at the Capitol, and said during an October debate that the former president should testify in compliance with a subpoena from the Jan. 6 committee.
The three candidates also sparred over the issue of abortion during an October debate, which became an election issue after the Supreme Court overturned 50 years of precedent protecting access to abortion, returning the issue to the states.
Murkowski said she would support "codification of Roe v. Wade" with limitations, while Trump-backed Tshibaka called for a nationwide ban on all abortions during the second trimester, or once an unborn child feels pain.
