Senator Lindsey Graham (R-SC) is facing growing discontent within his own party as a new Quantus Insights poll shows declining support among South Carolina Republicans. The survey of 600 registered voters found Graham’s overall approval rating at 41 percent, with 46 percent disapproving and 13 percent undecided. Among Republicans, only 34 percent said they would “definitely” support Graham in a primary, while 22 percent said they would “definitely” back a challenger and another 23 percent said they would “probably” support someone else. The data indicates significant vulnerability for the longtime senator as calls for new leadership grow louder within GOP ranks.

Businessman Mark Lynch has entered the race, aiming to capitalize on conservative dissatisfaction. His internal polling shows Graham leading 48 percent to 23 percent, but with a sizable 29 percent undecided—highlighting the potential for momentum. Lynch has accused Graham of straying from core Republican values by opposing Trump-backed reforms and supporting policies the former president criticized. With Graham often labeled a “RINO” by more hardline conservatives, the upcoming primary could be a serious test of his political future, especially if Lynch’s campaign gains further traction among the party’s base.
