On November 16, 2013, the Republican newcomer Vance McAllister, a businessman from Swartz, handily defeated State SenatorNeil Riser of Columbia in Caldwell Parish to claim the seat in a special election. McAllister led Riser, 54,449 (59.7) to 36,837 (40.3 percent), with all 981 precincts reporting. McAllister won fourteen of the twenty-four parishes in the district, including large margins in Ouachita and Rapides. McAllister had criticized Jindal for not extending Medicaid to qualified poor Louisianians and Riser had endorsed the refusal. The election was seen as a rejection of Governor Piyush "Bobby" Jindal's efforts to have the seat vacated and to replace Alexander with his hand-picked candidate in a low-turnout special election. The runoff turnout was less than 19%, three percent less than what it had been in the primary.
Changed political party (Alexander changed party affiliation from the Democratic Party to the Republican Party mere hours before the expiration of the deadline to qualify to run for office. Alexander's Party change at the last moment violated no election laws. Alexander's last minute move deprived the Democratic Party of the ability to replace Alexander on the ballot with another Democratic candidate. Another Democratic candidate had indeed qualified to run, but this candidate was a long shot and did not have the financial support of the Democratic Party establishment. Alexander won re-election easily as he was virtually unopposed.
