Darline Graham wins South Carolina GOP Senate runoff

Sen. Darline Graham, President Trump's endorsed candidate, won the Republican nomination Tuesday to fill the Senate vacancy created by her brother Lindsey Graham's death, per the AP. Why it matters: The victory underscores Trump's continued sway with Republican voters and positions Graham as the odds-on favorite to win a full term in November. Graham, 62, will be heavily favored against Democrat Annie Andrews in November. Democrats have not won a U.S. Senate election in South Carolina since 1998
