CHARLESTON, S.C. (AP) - A congressional primary along the South Carolina coast has emerged as a free-for-all driven more by personality than debate over party direction.
Former Gov. Mark Sanford headlines the list of 16 candidates. He's attempting a comeback almost four years after disclosing an extramarital affair with a woman who's now his fiancee.
The primary is Tuesday, with the probable GOP runoff set for early April.
The nominee will be favored in the May 7 general election to succeed Tim Scott, the congressman who's now in the Senate.
Scott became the South's first African-American senator since Reconstruction when Gov. Nikki Haley appointed him to the seat after fellow Republican Jim DeMint resigned. Scott joined the Senate in January.Copyright 2013 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
