Indian-American Raja Krishnamoorthi has registered a big win in the Democratic Congressional primary in the US state of Illinois by defeating the state senator.
Republican Mark Kirk defeated Illinois Treasurer Alexi Giannoulias in one of the nation's ugliest and most closely watched Senate races.
Krishnamoorthi, 43, won the Chicago-area US House of Representatives seat, the 8th Congressional District, vacated by Tammy Duckworth who won Illinois's US Senate seat.
