Graham Faces Multiple Challengers in 2026 GOP Primary

South Carolina Senator Lindsey Graham is seeking reelection in 2026 and faces a competitive GOP primary, with challengers including former Lt. Gov. André Bauer, Greenville businessman Mark Lynch, and Ethan Holliman. Bauer, a strong 'America First' conservative and longtime Trump ally, criticizes Graham for not being conservative enough and for his lengthy tenure. Despite a previously fluctuating relationship with Donald Trump, Graham has secured endorsements from Trump, Governor Henry McMaster, and Senator Tim Scott. Graham remains influential in the Senate and has recently supported Trump-backed legislation on border security and national defense. Other candidates in the race include several Democrats, independents, and a Libertarian. The Republican primary is expected to be the most competitive phase given South Carolina's GOP dominance.
