The state’s two Democratic Senate candidates are scheduled to debate three times this week, although it could be the last time they meet face-to-face in front of the voters before the Aug. 11 primary.

Rep. Mazie Hirono and former Rep. Ed Case were to appear jointly at an AARP-sponsored issue forum Tuesday morning, at a Hawaii Public Radio debate on Wednesday evening and on PBS Hawaii on Thursday evening. The latter two events were scheduled to be broadcast live.

Case said in a release that Thursday will be the last time they meet because Hirono “has refused all other debates including four primetime statewide debates on our main television stations.”

The winner will face former Gov. Linda Lingle (R) in November in a race Roll Call rates as Leans Democratic.
