Former President Donald Trump's endorsement power is being scrutinized in two high-profile Republican primary races, as candidates in South Carolina and Georgia compete for his support while voters weigh his influence at the ballot box.

In South Carolina's gubernatorial race, Trump has endorsed Lieutenant Governor Pamela Evette, but the endorsement has not guaranteed her victory among Republican primary voters. Representative Nancy Mace characterized the race as "a dog fight," suggesting Trump's backing has not resonated strongly with grassroots Republicans in the state's GOP primary.

Republican candidates in the South Carolina governor's race reportedly went to significant lengths to secure Trump's endorsement. Despite receiving his support, Evette faces continued competition from other candidates who are challenging the strength of the former president's influence in the race.

Meanwhile, in Georgia, Trump has not yet made an endorsement in the Republican Senate primary runoff. The race features Representative Mike Collins and Derek Dooley, a former football coach, who are competing to challenge Democratic Senator Jon Ossoff in the general election.

Both races are being closely watched as indicators of Trump's continued influence within the Republican Party and his ability to shape primary outcomes through endorsements. The results could provide insight into whether Trump's backing remains decisive in Republican contests or if other factors are playing larger roles in voter decision-making.
