WHY THE AP CALLED SOUTH CAROLINA FOR LINDSEY GRAHAM:
The Associated Press declared Republican Sen. Lindsey Graham the winner of South Carolina's Senate race at 9:35 p.m. EST, after an analysis of ballots statewide concluded there were not enough outstanding to allow Democratic challenger Jaime Harrison to catch up.
With 56% of the expected vote in, Graham led Harrison by nearly 13 percentage points.
Graham largely mirrored President Donald Trump's 2016 performance across the state, piling up significant margins. Votes for Harrison in the Democratic areas surrounding South Carolina's capital city of Columbia were not nearly enough for him to catch up.
Graham has represented South Carolina in the Senate since 2003.
