Former President Donald Trump and former U.N. Ambassador Nikki Haley are the frontrunners in the Alaska GOP presidential primary.

Despite dropping out, businessman Vivek Ramaswamy remains on the ballot.

Voting is restricted to registered Republicans and takes place between 3 p.m. and 8 p.m.

Alaska will allocate its 29 national convention delegates based on primary results, with a 13% vote threshold for candidates to earn delegates.

The chosen delegates will be finalized at the Alaska Republican Convention in April.

Preliminary primary results are expected to be announced by 9:30 p.m.
