Large-scale legal challenges of election ballots have not happened here as they have in key swing states on the mainland. But the broad issue of mail-in ballots has come up for the second straight general election in a Maui County lawsuit.

This time County Council candidate Kelly King contends that a higher-than-normal percentage of sealed mail-in ballots were rejected by County Clerk Moana Lutey. The clerk had flagged 1,069, primarily due to signature deficiencies.

Hawaii’s vote-by-mail system was built pretty robustly, but it seems difficult to lock down every single vulnerability.
