U.S. Rep. Mike Simpson has won a tenth term in Idaho's 2nd Congressional District, defeating former Democratic challenger Jennifer Martinez.
The congressional race was one of the quietest in the state.
Martinez was a first-time candidate and works as a community advocate in Twin Falls.
She campaigned little after announcing she was running for the seat.
Neither candidate participated in a statewide debate.
The 2nd District encompasses the eastern half of the state and is home to farms and ranches.
It also has the Idaho National Laboratory nuclear facility and numerous churches and temples representing a strong presence of The Church of Jesus Christ of Latter-day Saints.
