Nearly one-fourth of Hawaii’s registered voters have already cast their ballots for today’s general election, thanks to early-voting methods such as mail-in ballots or early walk-in at satellite city halls or civic hubs. To the remaining three-fourths: Make the time to head to your polling precinct, to do your part to counter Hawaii’s notoriously low election turnout. Polls open today from 7 a.m to 6 p.m.

More than 180,000 have already voted, out of 756,751 registered voters for the general election, said the state Office of Elections.

And an important reminder: For the first time ever, election-day registration is open for residents who are eligible to vote but haven’t registered. To do so: Go to the polling precinct as determined by your home address — see olvr.hawaii.gov/altpollingplacesearch.aspx or call (808) 453-VOTE — with a form of acceptable ID (such as a Hawaii driver license, military ID or passport) plus a current utility bill, bank statement, paycheck or other official document showing your name and address.

Another timely reminder: The proposed constitutional amendment about a school surcharge on investment property is moot, even though it appears on the ballot. The question was invalidated by the Hawaii Supreme Court last month, but due to preprinting, was unable to be physically deleted.

This is not to be confused with a separate question on whether to convene a convention to amend the state Constitution, which is still alive. Let’s hope objective signage or information at polling precincts will clarify this for voters , since it’s bound to cause confusion.

Here’s a recap of the Star-Advertiser editorial board’s endorsement for Oahu’s contested races. Ultimately, of course, the choice is yours. Take the time to have a say in your, and Hawaii’s, future.
