(CNN) – Hours before Vice President Joe Biden headlines a fundraiser in California for Sen. Barbara Boxer, a new survey indicates that the race between the three-term Democrat and Carly Fiorina, her Republican challenger, remains tight.
According to a Field Poll released Thursday morning, 47 percent of California voters say they support Boxer, with 44 percent saying they back Fiorina, and nine percent undecided. Boxer's three point advantage is within the survey's sampling error.
The poll indicates that Boxer leads by eight points among crucial independent voters.
Fiorina, the former Hewlett Packard CEO, who was also an economic adviser and surrogate for Sen. John McCain's White House bid, beat out two other rivals in the GOP primary earlier this month.
Boxer led Fiorina by 4 points in a Reuters/Ipsos poll late last month, the only other non-partisan survey conducted since the June 8 primary.
According to the Field Poll, 42 percent approve of the job Boxer's doing in the Senate, with 43 percent saying they disapprove. And her unfavorable rating now stands at 52 percent.
The survey indicates that more Californians are now familiar with Fiorina. Nearly two in three voters in the Golden State can now offer an opinion of her, nearly double the level of people familiar with her in January.
Biden headlines a fundraiser for Boxer Thursday evening in Atherton, California. President Barack Obama traveled to California twice this year to help raise campaign funds for Boxer.
Earlier in the day, the vice president is the main attraction at a campaign event in Oregon for Rep. Kurt Schrader, who faces a tough re-election battle.
The Field Poll was conducted June 22-July 5, with 1,005 California voters questioned by telephone. The survey's overall sampling error is plus or minus 3.2 percentage points.

Maybe Carley is the best solution – she can down-size California and outsource all the jobs to India - or maybe Mexico.
Her record is too long to ignore. Un-American.
Boxer has done nothing to deserve reelection. Time for change, as the last change, was a MISTAKE.
Hey Californians... if you think your state is in tip-top shape economically, I'd recommend you cast your vote for those who have made your state one of the most fiscally solvent in the country. Oh wait...
California has been run by "progressives" (read: embarrassed liberals) for a generation now (and no, Arnie is NOT a conservative) and I think the results of a womb-to-tomb nannystate clearly speak for themselves. California is in worse shape than Greece is, and Greece has all but collapsed.
Still want to vote for Boxer?
Why on earth the citizens would want Boxer is beyond me!
Boxer is done and will loose this November! She has been the biggest mistake California has ever elected. Time for her to go and put some common sense back into California!
and too entrenched with the beltway crowd.....time for new blood.....
Go Barbara! You are the best choice. California is too smart to choose otherwise.
BTW your hair looks better than hers as well.
I don't like Boxer but she is lesser of the 2 evils and I may end up voting for her as I definitely don't want Fiorna to win.
"Box" has become a professional politician. Don't you remember some of her rhetoric this past year or so when she decried threats to her job? She has become a Pelosi follower rather than a supporter of her own constituency and the country. Vote her out.
I'm a bit confused...how can Fiorna run at all? Doesn't anyone remember how much she damaged HP, and the scandal under which she left?
Biden showed up? That should clinch it for Carly!
Will you ever learn? Are there really that many liberals in the state where youd be dumb enough to re-elect Boxer? Have you not looked at the troubles your state is in?! Why would you reward Boxer?
Go ahead, keep re-electing the people that have gotten us to where we are today. Just dont expect things to be much different or improved.
Fiorina has to be happy that the gaffe-machine Biden is coming.
Of all the dumb liberals this one needs to be ousted ! Nah, never will happen in California!
The people in CA are craizer than I think they are if they elect Carly Fiorina. This woman almost destroyed HP and you want to elect her to Congress! This is the same woman who gave HORRIBLE advice to John McCain!
Think twice about that CA, think twice!
California does not need any Republicans in power. I have friends in every sector of California's middle-class and corporate sector and we all agree that Republicans would hurt our economy more than they could ever help it.
Keep Boxer in her Senate seat California.
Fire All incumbents!
They have had their chances over the last four decades to represent the people and have failed.
This goes for John McCain as well in AZ. It does not matter what party you represent because they is your problem to start with, you were supposed to represent the people.
boxer is old , arrogant, been there way ,way to long... she is whats wrong with washington.....new blood ,,,both parties...send her to the old folks home...
Anyone who could support a failed CEO like Carly is completely irresponsible. Do you realize she was FIRED? I know her style, I worked at HP. Please do not bring this woman into politics.
The era of being coddled by govt from birth to death is over.
Boxer has always been an outstanding Senator who fights for the people of California and takes her oath to serve seriously. Republicans are all about corporations and their best interests and that's exactly what Fiorina represents. She is failed corporate America who abuses their employees, has no social or moral responsibility to their communities, and Fiorina herself sent millions of her company's jobs overseas. She's no friend of the People. She's just a typical corporate Republican.
Boxer gets things done and she was the first one to catch BP in their lies by demanding access to video of the oil well gusher. We need champions of the People – the Democrats- not more corporate-kissing Republicans who sell us out for big corporate campaign money.
We are fortunate here in California that Carly Fiorina is willing to work for us in the Senate. She did outstanding work as CEO of Hewlett Packard, the results of which they now fully recognize and are enjoying the benefits from.
As Californians get to know Carly Fiorina better coming up to November, Harry Reid and Barack Obama wil lose one more yeswoman. Of course, Harry won't mind...he'll be gone too.
Nice to see that of all the things that Joe "foot in mouth" Biden could be doing he back on the campaign trail trying to drum up support for a failed presidency.
I'm voting for Boxer and I LOVE her hair.
Im no fan of Boxer,but if Californians elect Carly,you know this state is going off the edge.
