OAHU (HawaiiNewsNow) - Former Hawaii Congressman Ed Case is again vying to serve in the House of Representatives.
Election officials said the Democrat filed his nomination papers on Tuesday morning for Hawaii's 1st Congressional District, which encompasses the densely-populated urban areas of Honolulu. Six other Democrats are in the race, including former Attorney General Doug Chin.
Fellow Democrat Colleen Hanabusa, who currently represents the district, is running for governor against incumbent David Ige.
Case's entry is another twist in an already busy election cycle.
Hawaii's primary election will be held Aug. 11.
Case represented Hawaii's 2nd Congressional District from 2002 to 2007. In 2006, he unsuccessfully challenged then-Sen. Daniel Akaka in the Democratic primary.
Four years later, he tried to return to Congress but was bested by Hanabusa.
And in 2012, he lost a primary election battle to Mazie Hirono for the U.S. Senate seat vacated by Akaka.
Case is joining an already crowded field vying for the 1st Congressional District seat in the U.S. House.
Also running: state Reps. Beth Fukumoto and Kaniela Ing, state Sen. Donna Mercado Kim and City Councilman Ernie Martin.
