In the Palmetto State, there is a special GOP primary for Senate.
Voters head to the polls on Aug. 11 in several states, including South Carolina, Wisconsin, and Minnesota.
Key races will determine candidates for the 2026 midterms in November, which have seen a growing tension between two wings of the Democratic Party.
That tension is coming to the fore in Wisconsin, where there is a test of the power of democratic socialists in the Democratic gubernatorial race.
Meanwhile, Republicans are fighting to keep control of the Senate, where multiple members have decided not to run for reelection.
Sen. Lindsey Graham’s (R-S.C.) unexpected death left a vacancy that was quickly filled by his sister, but could see a different replacement depending on how the primary shakes out on Tuesday.
Here are the key races to watch.
South Carolina
Graham’s sister, Darline Graham, is fighting to keep her brother’s seat, but is facing competition from multiple leading Republicans.
Rep. Ralph Norman (R-S.C.), Rep. Russell Fry (R-S.C.), and former Rep. Mark Sanford (R-S.C.) are among the 10 Republican candidates seeking that seat.
Lindsey Graham had won his primary on June 9, but died from a suspected aortic rupture on July 11.
His sister is set to serve the rest of his current term, which ends on Jan. 3, 2027.
President Donald Trump has endorsed her to take Lindsey Graham’s place after that period.
There will be a runoff on Aug. 25 of the top two vote-getters if no candidate gets a majority in the primary.
The winner will face doctor Annie Andrews, a Democrat, in November.
Darline Graham does not have a platform on her campaign website, but has cited her experience in state government in making the case that she should get six years in the Senate.
“Trust me, I have learned a lot already, so I think I have experience,” she told reporters.
During her short tenure in the Senate, Darline Graham put forth a bill to sanction Russia and Iran. The legislation, named after her brother, passed on Aug. 7.
Norman and Fry are running on conservative platforms that include securing the border, lowering the cost of living, protecting the Second Amendment, and confronting China.
Sanford’s biggest issue is the national debt and out-of-control spending in Washington.
