Darline Graham and Ralph Norman will face each other in a runoff for South Carolina's Republican Senate primary. This runoff, scheduled for August 25, is expected to determine the state's next senator. Graham, the late Senator Lindsey Graham's sister, benefited from incumbency advantages and President Trump's endorsement. Norman positioned himself as a proven conservative based on his voting record. The Republican nominee is heavily favored to win in November against Democrat Annie Andrews, as South Carolina is a strongly Republican state. No candidate secured the required majority in the initial nine-candidate race. Graham, a political newcomer, aims to continue her brother's constituent work and support Trump's agenda. Norman, a hard-line conservative and member of the House Freedom Caucus, is also seeking the nomination. This runoff will test President Trump's influence within the Republican electorate. The two finalists have a limited time to gain support from voters whose candidates were eliminated.
