The 2020 Alaska Democratic presidential primary had been scheduled to take place on April 4, 2020, in the Democratic Party primaries for the 2020 presidential election, but in-person voting was cancelled due to the COVID-19 pandemic and mail-in voting was extended to April 10, 2020. The Alaska primary was a closed party-run primary, with the state awarding 19 delegates to the 2020 Democratic National Convention, of which 15 were pledged delegates allocated on the basis of the results of the primary. Voters cast ranked-choice voting ballots, with a voter's ballot counting for four ranked backup choices if their original choice was in last place and below the 15 percent threshold for winning delegates.
