The National Republican Senatorial Committee raised concerns about Oz’s lackluster polling and fundraising on at least three separate occasions in recent weeks, multiple sources told POLITICO.

On a donor call last week that focused on Senate races throughout the country, NRSC officials discussed Oz’s poor performance in polls, including his high unfavorability ratings, said a person on the call.

“It was an alarm bell,” the person said, adding that Oz’s poor image among voters is “really freaking everybody out.”…

The NRSC officials on the call “brought to everyone’s attention that there’s definitely a path to winning the Senate even if Oz loses, and that seemed to be a very big concern on the call — is that Oz just has not hit his stride as a candidate,” the person on the call last week said. “The viewpoint was it’s more important to reallocate money to seats that we feel we can win.”
