BOISE, Idaho (AP) — US Rep. Mike Simpson will go on to serve a ninth term in Idaho's 2nd Congressional District after defeating former Democratic challenger Richard Stallings.

Tuesday's election is the second time the two opponents have faced off for the same congressional seat. Stallings held the seat from 1985 to 1993. However, he lost to Simpson by 8 percent in 1998.

The 2nd District encompasses the eastern half of the state and is home to farms and ranches, the Idaho National Laboratory nuclear facility, and the churches and temples representing a strong presence of The Church of Jesus Christ of Latter-day Saints.
