A Kauai mayoral debate has collapsed into a one-candidate town hall, leaving voters with less to compare before election day.

• Bernard Carvalho pulled out of the debate a day before it was set to happen.
• His campaign said the rules came too late and left too little time to prepare.
• Rival Mel Rapozo said he was disappointed after two weeks of prep, and that debates exist for voters, not candidates.
• The event now becomes a solo town hall with Rapozo on KKCR radio, also streaming online.

Outlook: With no head-to-head matchup on the calendar, Kauai voters may head to the polls without seeing the two candidates tested side by side.
