Polls have begun closing in primary elections across the country, as voters in states such as Wisconsin, Minnesota and South Carolina pick their party’s candidates ahead of the 2026 midterms.
In South Carolina, polls closed at 7 p.m. ET as Republican voters narrow their choices to be the GOP nominee to succeed the late Sen. Lindsey Graham.
Sen. Darline Graham, R-S.C., will advance to a runoff election for the nomination, according to the Associated Press. Graham was appointed to the Senate to fill her brother’s seat for the remainder of his term, which ends in January, and was endorsed by President Donald Trump for a full term.
Rep. Ralph Norman, R-S.C., will also advance to the runoff, setting up a showdown with Graham for the nomination later this year.
In Minnesota and Wisconsin, polls are set to close at 9 p.m. ET. In both states, progressive Democrats are facing off with more moderate Democratic candidates — a crucial test as the party’s left flank surges across the country.
Progressive Lt. Gov. Peggy Flanagan is facing centrist Rep. Angie Craig, D-Minn., for the Democratic nomination for an open Senate seat in Minnesota. In Wisconsin, Democratic socialist Francesca Hong is the frontrunner to be the Democrats’ gubernatorial nominee. Incumbent Wisconsin Gov. Tony Evers, who is retiring, has endorsed Milwaukee County Executive David Crowley to succeed him.
