The Democratic Party of Hawaii announced this week how it will hold its Party-run Presidential Primary April 4.

It will include vote-by-mail and ranked choice voting.

“We’re excited to offer our membership the ability to engage in the Party-run Presidential Primary through mail-in voting, and with so many great Democratic candidates, it is a positive development that our members will be able to rank their top three presidential candidates,” said Interim Party Chair Kate Stanley via press release.

The Democratic National Convention, which holds its convention next July in Milwaukee, Wisconsin, approved the local party’s delegate selection process.

A DNC-vetted vendor will design and monitor the voting process “from ballot design to certification of the final count.”

Registered Hawaii voters will also be allowed to join the party and vote during the polling hours of 7 a.m. to 3 p.m. A list of polling sites will be announced in late January.

In 2016, Vermont Sen. Bernie Sanders defeated former Secretary of State Hillary Clinton in what was then referred to as a presidential preference poll.

That same spring businessman-turned-reality-TV-star Donald Trump bested Texas Senator Ted Cruz in the Hawaii GOP’s presidential caucus.

The Hawaii Republican Party is identified as holding a caucus on March 10.

It is unclear how many Democratic candidates will still be in the race following all the caucuses and primaries in February and March. They include Super Tuesday on March 3, which includes California and Texas.
