You have to examine 'Ranked Choice Voting'. It destroys the 2 party system and facilitates fraud - just about always by the Dems. In the previous senatorial race by Murkowski, a really talented young 'Republican' woman ran against her and gained more votes than Murkowski... but since it was 'ranked choice', both qualified for the general election.
Since Dems could vote for whoever they wanted and I don't even remember if there was a real serious Dem candidate, they voted for the Democrat RINO - as usual. Murkowski's whole purpose in Alaska elections is to ensure that no true Republican candidate ever wins through to office.
