Arnold Schwarzenegger has decided not to run for US Senate, the former Republican governor and reality TV star announced.

“I’m deeply flattered by all of the people who have approached me about running for Senate, but my mission right now is to bring sanity to Washington through redistricting reform like we passed here in California,” Schwarzenegger said in a Facebook statement posted Sunday morning.

“Gerrymandering has completely broken our political system and I believe my best platform to help repair it is from the outside, by campaigning for independent redistricting commissions. Thank you for your kind messages and all of the support and I hope you’ll join me in my battle against gerrymandering with the same enthusiasm,” he added.

The “Terminator” star and former host of “Celebrity Apprentice” had been eyeing a 2018 US Senate bid, Politico reported days ago.

But Schwarzenegger, 69, ultimately passed on the opportunity, which may have pit him against the Democratic incumbent, Dianne Feinstein, who will be 85 on Election Day.

It was announced last week that the former body builder would be leaving “Apprentice.”

“Arnold Schwarzenegger isn’t voluntarily leaving the Apprentice, he was fired by his bad (pathetic) ratings, not by me. Sad end to great show,” President Trump, an executive producer on the show, announced on Twitter.

“You should think about hiring a new joke writer and a fact checker,” Schwarzenegger shot back.
