Some polls in the last few months have found Dianne Feinstein in trouble for reelection, but not us: she has a solid approval rating and double digit leads over a handful of hypothetical Republican opponents.
51% of Californians approve of the job Feinstein is doing to 38% who disapprove. Her numbers have barely moved over the course of this year- the other time we polled the state, in late January, she was at 50/39. Feinstein has the party base pretty much unified behind her, with 76% of Democrats approving to only 11% who disapprove. She also has a higher than normal amount of crossover support with 19% of Republican giving her good marks, and that helps her overcome a poor 37/46 spread with independents.
The only well known Republican challenging Feinstein, although she is perhaps more infamous than famous, is prominent birther Orly Taitz. Taitz's crusade hasn't brought her much name recognition- 77% of Californians don't have an opinion about her. And among those who do have one only 4% see her positively to 19% with a negative opinion. Even with Republicans she's at only 4/22. Suffice it to say she would not present a very strong challenge to Feinstein- she trails in a hypothetical contest 56-29.
We also tested some other Republicans against Feinstein who would presumably make stronger opponents than Taitz but the closest any of them comes is Feinstein's 2000 opponent, Tom Campbell, and he still trails by 15 points at 53-38. 2010 Republican Gubernatorial runner up Steve Poizner trails Feinstein by 19 points at 54-35.
Last year's GOP Senate nominee, Carly Fiorina, trails Feinstein by 20 points at 56-36. That is a good reflection of Feinstein's strength relative to Barbara Boxer- Boxer defeated Fiorina by only 10 points last year, so Feinstein is about 10 points stronger. If Republicans were going to pick up a Senate seat in California they probably needed to do it last year.
Finally Congressman Devin Nunes, who recently threatened to challenge Feinstein before walking it back, trails her by 24 points at 55-31.
If Dianne Feinstein wants another term in the Senate it doesn't look like she will have too much trouble getting it.
