Republican Greg Davis and Democrat Travis Childers have won their party nominations during runoffs in north Mississippi's 1st Congressional District.

They will compete in the November general election for the chance to take office in January.

Davis and Childers get no immediate reprieve from campaigning in the 1st District because they'll compete April 22 in a special election.

The winner of that race will serve the rest of this year to finish the two-year term Republican Roger Wicker started in January 2007. Wicker was appointed to fill a seat left vacant by the resignation of U.S. Sen. Trent Lott.

Childers, the Prentiss County chancery clerk, defeated state Rep. Steve Holland on Tuesday. Davis, the mayor of Southaven, defeated former Tupelo Mayor Glenn McCullough, Jr.
