What to expect in elections in South Carolina, Georgia and Oklahoma

South Carolina Republicans will determine on Tuesday who will succeed late Sen. Lindsey Graham on the ballot for the November midterm election. Graham's sister, Sen. Darline Graham, is facing Rep. Ralph Norman in Tuesday's runoff election, both of whom were the top vote-getters in the special primary on Aug. 11. Darline Graham was appointed to serve out the remainder of her brother's term, which concludes early next year.

While she has no prior elected office experience, she has focused on domestic issues during the campaign, drawing support from President Trump. However, her lack of preparedness in foreign policy has raised concerns about her candidacy for a full term. At a recent debate, she struggled with questions about Taiwan and the South China Sea, with Graham stating she is not well-informed on national security compared to her late brother.

When asked about specific proposals on these issues, she offered no plan, stating they would be addressed once in the Senate. Graham, who is already serving in the Senate, will face Dr. Annie Andrews, the Democratic primary winner in June. Despite South Carolina being a solidly Republican state with only one Democratic representative in Congress, the race remains significant for Democrats due to fundraising potential.

President Trump endorsed Darline Graham, campaigning for her and providing financial support to her campaign.
