Robert “Bob” Marx, a Hilo attorney, ran for Hawaii's 2nd Congressional District in the 2012 elections. The seat opened up after Rep. Mazie Hirono announced her candidacy for retiring Sen. Daniel Akaka's post.
The 2nd Congressional District includes Kauai, Maui, the Big Island, Lanai, Molokai, Kahoolawe, the Northwestern Hawaiian Islands and the north and west regions of Oahu. About 680,000 people live in the district, or roughly half of all the state's residents.
In the August 2012 Democratic primary, Marx received only 4 percent of the vote in the face of strong competition from Honolulu City Council member Tulsi Gabbard, former Honolulu mayor Mufi Hannemann and former Office of Hawaiian Affairs chief advocate Esther Kiaaina. Gabbard, who received 54 percent of the vote, will challenge Kawika Crowley, the Republican nominee, in November 2012.
