A plurality of Republican voters in California are up in the air about the 2010 Senate, but those who have an opinion are split evenly between GOP candidates Carly Fiorina and Chuck DeVore, according to a USC/Los Angeles Times Poll conducted Oct. 27 through Nov. 3 by Greenberg Quinlan Rosner Research.

Forty percent of registered Republicans said they were undecided about whom they want to take on Democratic Sen. Barbara Boxer next November. Twenty-seven percent each said they would back former Hewlett-Packard CEO Fiorina, who officially entered the race last week, and Devore, a state assemblyman from Irvine, Calif. who has been campaigning for several months.

Fiorina has a far higher profile in political circles and the media than DeVore given her past leadership of tech titan H-P and a stint as advisor for 2008 Republican presidential nominee John McCain, but that doesn't appear to have trickled down to the average California voter. The pair had some of the lowest name recognition rates among a long list of California politicians and candidates -- 29 percent could identify Fiorina and just 19 percent could identify DeVore.

Approval ratings for California's three political leading ladies have sunk, according to a Field Poll of registered voters conducted Sept. 18 to Oct. 5.

California voters' opinions of the job performance of House Speaker Nancy Pelosi, who represents California's 8th District, and Sens. Dianne Feinstein and Barbara Boxer are at their lowest levels in the past two years.

Pelosi, who has become a poster child for liberal Democrats and the focus of constant GOP attack, has the lowest approval ratings of the three -- 34 percent to 44 percent disapproval. Twenty-two percent had no opinion. The margin of error was plus or minus 3.2 percent.

The Republican primary for California Senate is up in the air with 59 percent of registered Republicans undecided about whom they will vote for next year, according to a Field Poll conducted Sept. 18 to Oct. 6.

Among those voters who do have an opinion, establishment favorite Carly Fiorina, the former Hewlett Packard CEO, had 21 percent support while 20 percent back Chuck DeVore, a conservative assemblyman and official candidate. That represents a drop compared to March for Fiorina, who has opened an exploratory committee, but has yet to formally enter the race. Then, the Field poll had Fiorina at 31 percent and DeVore at 19 percent.

Since then, DeVore has been actively reaching out to the state's GOP base, including a big presence at the California Republican Party convention last month. Fiorina skipped the event to complete chemotherapy treatment for breast cancer. He also reported raising more than $330,000 in the quarter, hardly the $2.4 million incumbent Sen. Barbara Boxer had in the bank mid-year, but a respectable showing for the underdog candidate.

California Sen. Barbara Boxer earns less than 50 percent of the vote in hypothetical match-ups against two prospective Republican challenger, according to a Rasmussen Reports poll conducted Sept. 23.

Boxer, who is running for a fourth term in 2010, leads former Hewlett Packard CEO Carly Fiorina 49 percent to 39 percent and conservative state Assemblyman Chuck DeVore 46 percent to 37 percent among likely California voters. The margin of error is 4.5 percent.

For Boxer, that is an improvement over her showing in a July survey, when she led Fiorina by just 4 percentage points.

A Research 2000/Daily Kos poll of 600 likely voters conducted Aug. 9-12 shows Republican Meg Whitman, the former CEO of eBay, and Democrat Jerry Brown, the current state attorney general and a former governor, leading their respective fields for the open 2010 governor's race in California.

In a hypothetical general election matchup between the two, Brown bested Whitman 42 percent to 36 percent, with 22 percent undecided.

Brown also led San Francisco Mayor Gavin Newsom in a hypothetical Democratic primary matchup, 29 percent to 20 percent -- but a whopping 51 percent said they were undecided.

On the Republican side, Whitman led former Rep. Tom Campbell and state Insurance Commissioner Steve Poizner in the GOP primary: 24 percent for Whitman, 19 percent for Campbell, 9 percent for Poizner and 48 percent undecided.

Republican Gov. Arnold Schwarzenegger is term-limited in 2011. CQ Politics rates the governor's race Leans Democratic.

Former corporate executive Carly Fiorina, a Republican, runs a surprisingly close race against three-term Democratic Sen. Barbara Boxer in a 2010 California match-up, trailing her by only 45 percent to 41 percent with 7 percent preferring someone else and 7 percent undecided, according to a Rasmussen Reports poll conducted July 22. The margin of error is 4.5 points.

Boxer's favorable-to-unfavorable ratio is 50 percent to 47 percent with 3 percent unsure, and the lesser-known Fiorina is seen unfavorably by 35 percent, favorably by 30 percent but has 35 percent of voters who don't know enough about her to be sure.

While incumbents polling below 50 percent are viewed as vulnerable, Rasmussen says "a Democrat running in a heavily Democratic state like California is often able to overcome weak poll numbers."

Three term Democratic Sen. Barbara Boxer holds comfortable leads in match-ups against potential GOP challengers in 2010, but voters are almost evenly divided when asked if they want to re-elect her, according to a Field Poll conducted Feb. 20 - March 1.

While Field says 44 percent are not inclined to back her again compared to 43 percent who are, it notes that these numbers are better than they were the last two times she ran and that she eventually won by comfortable margins.

She leads Gov. Arnold Schwarzenegger 54 percent to 30 percent and former Hewlett Packard chief executive Carly Fiorina by 55 percent to 25 percent.

In a hypothetical Republican primary to choose a candidate to run against Boxer, Schwarzenegger leads Fiorina 31 percent to 24 percent with Assemblyman Chuck DeVore polling 9 percent. If Schwarzenegger doesn't run, Fiorina would lead DeVore 31 percent to 19 percent. But in either case, these match-ups should be take n with a grain of salt because both scenarios have huge undecided numbers.
