Overview
- President Trump agreed to join a 5:30 p.m. tele‑rally on Monday to urge South Carolina Republicans to back Sen. Lindsey Graham ahead of Tuesday’s primary.
- Graham faces real risk of falling below the state’s 50% threshold that would force a June 23 runoff, a danger highlighted by mixed late polls that showed him both under and over the mark.
- Mark Lynch, Graham’s principal challenger, has self‑funded his campaign with roughly $5 million and made Graham’s backing for the U.S. role in the Israel‑Iran conflict the central issue of his challenge.
- Prominent pro‑Trump media figures publicly celebrated the possibility of Graham’s defeat even as Trump denounced Lynch and mobilized support for the incumbent.
- The outcome will test how decisive Trump’s endorsements remain in Republican primaries and could reshuffle intra‑party power if South Carolina voters punish a senator for his Iran policy.
