Registered voters in the 1st Congressional District can cast their special-election ballots in person starting today.

More than 317,300 ballots have been mailed to voters in the district.

But the state Office of Elections says registered voters who failed to receive a ballot or have not yet mailed back their ballots can vote in person at the courtyard of Honolulu Hale.

With the exception of May 16, votes can be cast daily from 8 a.m. to 4 p.m. until May 20.

Votes will be tabulated and the winner will be announced May 22.

The field to replace former U.S. Rep. Neil Abercrombie includes Democrats Ed Case and Colleen Hanabusa, and Republican Charles Djou.
