Semafor's Burgess Everett explains how Democrat Annie Andrews defeated Darline Graham, the late Lindsey Graham's sister, for South Carolina's Senate seat, banking on an internal October poll showing her up 3 points and spending early while Republicans prioritized other races. Andrews raised $25 million to Darline Graham's nearly $2 million, aired an ad with her Republican father to court Lindsey Graham loyalists, and worked with Rep. Jim Clyburn to boost turnout.
