Gabbard, a 33-year-old rising star in the Democratic Party, was first elected to the US House of Representatives in 2012. She was re-elected to the Congress from Hawaii's 2nd District, defeating Republican Kawika Crowley.
Gabbard hardly had to campaign this election after running unopposed in the August 9 primary.
Instead, she and her political action committee have spent thousands of dollars helping fellow Democrats in Hawaii and on the mainland, the Huffington Post reported.
In 2012, Gabbard blew past former Honolulu Mayor Mufi Hannemann in the Democratic primary and then beat Crowley in the general, winning 77 per cent of the vote. She is the first Hindu ever elected to Congress.
