Sen. Lisa Murkowski ran against fellow Republican Kelly Tshibaka and Democrat Patricia Chesbro, but the battle was largely between the two Republicans.
Tshibaka was endorsed by Donald Trump, while Murkowski had the endorsements of several high-profile Democrats, including Sen. Joe Manchin.
Republican Sen. Lisa Murkowski defeated Democrat Patricia Chesbro and fellow Republican Kelly Tshibaka in Alaska to represent the state in the US Senate.
Her Republican challenger, Tshibaka, raised $4.8 million, spent $4.2 million, and had $692,428 cash on hand, as of October 19.
Murkowski benefitted from most of that spending, including a $6.1 million boost from the Senate Leadership Fund, a national Republican super PAC.
