A new poll shows that longtime Democratic Sen. Dianne Feinstein's job approval rating has all but collapsed in two large California counties. 

According to The Orange County Register, the survey was carried out by the Public Policy Institute of California and divided the state into regions.

Ten point drop

It found that just 30% of respondents in Orange and San Diego counties said they approved of Feinstein's performance, marking a more than 10% from the results of a similar poll conducted in March of last year.

Feinstein fared even worse among residents of the Central Valley, Inland Empire, and San Francisco Bay Area, who gave her an approval rating of just 28%.

The senator's one relative bright spot was Los Angeles, where the figure stood at 36%. Yet even there, Feinstein polled 10 points lower than she did last spring.

Fred Smoller is a political science professor at Chapman University, and he told the Register that has more to worry about from fellow Democrats than she does from Republicans.

"She’s under attack by her own party"

"A once very popular senator has lost a lot of support because, unfortunately, she’s perceived by both the left and the right as not well enough to do her job effectively," Smoller was quoted as saying.

"She’s under attack by her own party, (Rep. Alexandria Ocasio-Cortez) and the 'squad' who are calling for her to step down. She was once very popular but has declined tremendously," he added.

There have been growing concerns about Feinstein's cognitive prowess, something one of her Democratic colleagues spoke anonymously to the San Francisco Chronicle about last year.

"I have worked with her for a long time and long enough to know what she was like just a few years ago: always in command, always in charge, on top of the details, basically couldn’t resist a conversation where she was driving some bill or some idea," the lawmaker said before adding, "All of that is gone."

California congressman calls on Feinstein to resign

Meanwhile, New York Times congressional correspondent Annie Karni noted in an article published late last month that Feinstein had missed six votes and not participated in any committee hearings or caucus lunches after a long absence from Washington.

What's more California Democratic Rep. Ro Khanna made headlines last month when he released a statement last month asking her to step down.

"It’s time for [Sen. Feinstein] to resign," Khanna said in a tweet. "We need to put the country ahead of personal loyalty."

It’s time for @SenFeinstein to resign. We need to put the country ahead of personal loyalty. While she has had a lifetime of public service, it is obvious she can no longer fulfill her duties. Not speaking out undermines our credibility as elected representatives of the people.
