(AP) — Democrat Troy Carter won Saturday's special election for Louisiana's vacant U.S. House seat, defeating his state Senate colleague and ending an acrimonious, intraparty clash. Carter easily defeated Karen Carter Peterson in the race for Louisiana's only Democrat-held seat in Congress, handing a victory to the more moderate side of the party after Peterson planted herself firmly in the progressive camp.
