A majority of the Mississippi House of Representatives will be Republican for the first time since Reconstruction.
Republicans will control at least 62 of the 122 seats in the House when the Legislature convenes Jan. 3.
Some counties were still counting ballots Monday. GOP candidates held narrow leads in two other districts, so Republicans could gain an even bigger edge if those leads hold.
The Republican caucus is scheduled to meet later Monday to choose its nominee for House speaker, a post last held by a party member nearly 140 years ago.
The party also controls the state Senate, as well as all but one major statewide elected office. Last week, Republican Phil Bryant to succeed the Gov. Haley Barbour. Barbour could not run again because of term limits.
