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.

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.
