Actor Patrick Dempsey said Wednesday that he will not run for a Maine Senate seat, quashing speculation that the “Grey’s Anatomy” star and People magazine’s former Sexiest Man Alive was among those being considered to replace embattled Democratic nominee Graham Platner.

Platner has currently paused his campaign to mull withdrawing from the high-stakes Senate race following an accusation from a former girlfriend that he once sexually assaulted her. The oyster farmer and Marine veteran, who denies the allegation, had secured the Democratic nomination in June to go up against longtime Republican Sen. Susan Collins in November.

In an editorial published in the Portland Press Herald, Dempsey wrote that Mainers are facing challenges including housing, healthcare and education, and whoever is elected as Maine’s next senator should work to enact meaningful change.

“As I reflected on all of this, I kept coming back to one question: Do I truly want to serve in Congress?” Dempsey wrote. “After a lot of thought, I realized the answer is no. Not because public service isn’t honorable — it absolutely is. But because I believe I can contribute more effectively through the life I’ve already built.”

Dempsey did not endorse any other candidate from those currently teasing their interest in replacing Platner, nor did he name Platner. Instead, he wrote that the candidate should offer “a new approach to how we govern ourselves.”

“Most of all, I want integrity. That may sound idealistic today, but it shouldn’t,” he added.

Dempsey grew up in the Lewiston-Auburn area and is the founder of The Dempsey Center in Maine, which provides free care to people impacted by cancer.
