A Republican has won a House seat in Hawaii in the district where President Barack Obama grew up.

Representative-elect Charles Djou won the special election in a race against two Democrats. It is the latest triumph for the Republican Part as it seeks to take back control of Congress.

"It is a significant win. It is the birthplace of the president of the United States," RNC Chairman Michael Steele said a few hours after Djou sealed his victory over Democratic rivals Colleen Hanabusa and Ed Case.

The seat had been held by a Democrat for nearly 20 years. Djou campaigned against the ballooning national debt and the Democrats' out-of-control spending.

"We have sent a message that this congressional seat is not owned by any political party," Djou said. "It is not owned by any union. It is not owned by any special interest group. This congressional seat is owned by the people."

Djou hopes to be sworn in this week.
