South Carolina US Senate special (R): Republicans are running an accelerated, two-round contest for the late Lindsey Graham’s seat. ADForty-three percent of South Carolina Republicans voted for a Graham alternative just three months ago, in the regular primary. Ned Lamont, who turned 72 this year, is seeking a third term; state Rep. Josh Elliott, who’s 30 years younger, is challenging him from the populist left. Cooke bridged the Democratic Party’s divisions with endorsements from the center-left Third Way and Sen. Bernie Sanders, I-Vt. The winner will face Democratic Sen. Amy Klobuchar, whose entry into the race pushed it down on the GOP’s target list.
