On Tuesday, voters in South Carolina, Georgia, and Oklahoma will participate in various elections, including run-offs in South Carolina and Oklahoma, as well as a special election in Georgia. The elections come at a critical juncture, serving as precursors to November's midterm elections. In South Carolina, the race to replace the late Senator Lindsey Graham is ongoing, with Senate Darline Graham and Representative Ralph Norman vying for the Republican nomination. In Oklahoma, an expensive governor nomination fight between State Attorney General Gentner Drummond and former state Senator Mike Mazzei will be decided, while Democrats select a nominee for a US Senate seat. The outcomes of these elections have significant implications for the November midterms and could potentially test Trump's endorsement power. In Georgia, a special election is being held to fill an empty congressional seat following the death of a lawmaker. Additionally, Oklahoma voters will decide on two statewide ballot measures, including one that would add a voter identification requirement to the state constitution.
