FRANKFORT, Ky. (AP) - Eighteen candidates across the state are competing for five Congressional seats in Kentucky.

Former U.S. Rep. Anne Northup of Louisville is seeking her old job representing the state's 3rd District.

U.S. Rep. Geoff Davis from northern Kentucky is the only incumbent facing a challenge in the primary election. Democrat Michael Kelley is waiting in the general election.

An open seat in the 2nd District was created when U.S. Rep. Ron Lewis decided not to seek another term. Democrats David Boswell, a state senator from Owensboro, and Reid Haire, the Daviess County judge-executive, are challenging each other to take on Republican state Sen. Brett Guthrie in November.

U.S. Rep. Ed Whitfield, who represents Kentucky's 3rd Congressional District, is unopposed in the primary and will face Democratic challenger Heather A. Ryan in the fall.

Hal Rogers, Kentucky's longest serving representative, is the state's only congressman not facing an electoral challenge in 2008.
