‘Greys Anatomy’ actor Patrick Dempsey says he has no plans to run for Senate in Maine if Democratic Senate candidate Graham Platner drops out of the race.

Dempsey, who played neurosurgeon Dr. Derek Shepherd on the long-running ABC medical drama, wrote in an op-ed published by the Portland Press Herald Wednesday that he had been asked whether he would run for Senate.

While he said it was “flattering” to be considered, he decided against throwing his hat in the ring.

“I kept coming back to one question: Do I truly want to serve in Congress? After a lot of thought, I realized the answer is no,” Dempsey wrote.

“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,” he added.

Dempsey, a Maine native, founded The Dempsey Center amid his mother’s battle with ovarian cancer. She passed away in 2014. The center supports and provides care to cancer patients in honor of his mother.

“The Dempsey Center has shown me what’s possible when people put aside differences and focus on helping one another,” Dempsey wrote. “No one asks who you voted for before offering support. That’s the America I know. That’s what I want to see in the leader we send to the Senate.”

Platner has been facing calls to drop out of the Maine Senate race hours after a new allegation of sexual assault against him. He has denied the allegations but several of his closest allies in Congress have rescinded their endorsement.

Platner must drop out of the race before Monday so that the state Democratic Party committee can replace him on the ballot by July  27 in the crucial election against incumbent Republican Sen. Susan Collins.

Former state Senate President Troy Jackson filed paperwork Tuesday to replace Platner. Nirav Shah, a former director of Maine’s Center for Disease Control and Prevention, Maine Secretary of State Shenna Bellows, state Rep. Valli Geiger and state House Speaker Ryan Fecteau have all signaled they are interested in replacing Platner.
