While the former California governor is "very good friends" with the reality star, he admitted on Jimmy Kimmel Live! that he just wants the best person for the job to win.
"The key thing about all of this is it doesn't matter if it's Caitlyn or anyone else — to have a clear vision of where you want to go, what are the kind of changes you want to make and why are you qualified to become governor," he told Kimmel. "That’s what you have to convince the people."
Schwarzenegger added: "All the other stuff is all nonsense because the press will attack you no matter who you are. They attacked me but then, in the end, I won, so that was the main thing."
The 73-year-old served as governor from 2003-2011 after a recall election.
Schwarzenegger acknowledged that Jenner, 71, has a good a shot as any of the other candidates challenging Democratic incumbent governor Gavin Newsom in a potential recall election.
“Anyone has a chance because I think that the people are dissatisfied with what’s going on here in California," he insisted.
Schwarzenegger also revealed many of the candidates have already sought out his guidance. "Just about everyone that is thinking about running has called me [for advice]," he dished.
Apart from being close to the former Olympian, noting he has "the utmost respect for her," Schwarzenegger said he's "also very good friends with governor Newsom and I’m good friends with all the other people that have contacted me and have asked me for advice about running or not running and all those kinds of things."
To conclude, the Terminator star — who predicted at least another 100 candidates will throw their names in the mix — hopes whoever is chosen for governor will fix "the mess we are in right now," he said.
Last week, the KUWTK reality star announced she was officially "in" to run for governor, OK! reported. Jenner, who is a transgender rights activist and longtime Republican, is hoping to use her celebrity status to win over her constituents in the Golden State.
However, it looks like she's already having a hard time getting her famous family on board with her political aspirations. The Kardashian family will reportedly not campaign for Jenner after her messy divorce with momager Kris Jenner, and an OK! source recently revealed the family is "freaking out behind the scenes."
In addition, the family still appears to be traumatized after what they went through with Kanye West's failed 2020 presidential run.
Added the OK! source, "The family survived Kanye’s run and now they have to go through it again."
