AP Decision Notes: What to expect in South Carolina’s special U.S. Senate primary runoff

WASHINGTON (AP) — South Carolina Republicans will return to the polls Tuesday for the fourth time since June to replace the late U.S. Sen. Lindsey Graham on the fall general election ballot.

Graham won the June 9 Republican primary for renomination to the seat he first won in 2002, but his unexpected death on July 11 from an aortic tear created a vacancy not only for his current U.S. Senate seat but also as the party’s pick to compete for another six-year term.
