Susan Collins retains lead in Maine Senate race post-replacement

With Platner out and a replacement candidate still unselected as of July 11, 2026, incumbent Sen. Susan Collins (R-ME) maintains a polling lead in Maine. Even with a progressive replacement, Collins’ moderate brand and incumbency advantage likely ensure her lead persists through October 2026.
