This poll's a little suprising, since it's the first poll to find a very close race between Democratic AG Jerry Brown and Republican ex-eBay CEO Meg Whitman (the closest she had come in any previous poll was 6 points, actually an R2K poll from August). It's also the first poll to find some wide differentiation in general election performance between Whitman and her other two opponents, as Rasmussen finds 9 and 11-point leads for Brown over ex-Rep. Tom Campbell and Insurance Commissioner Steve Poizner. Compare that with September's Field Poll... or just with the trendlines from the previous Rasmussen poll.
Although Californians are understood to be in a surly mood these days, all the candidates clock in with positive favorables: Brown is at 48/41, Whitman is at 47/27, Campbell is at 40/20, and Poizner is at 36/26. I'm a little surprised at this level of name-rec for the Republicans, considering how little-known they have tended to be in other polls. Another tidbit that points to the effect of Rasmussen's likely voter screen: Barack Obama has a 55/43 approval -- a good number, to be sure, but most pollsters have had Obama in the low-to-mid 60s in California, as it usually tends to be one of his best states for approval ratings (in fact, given California's size, it's probably single-handedly responsible for keeping Obama's nationwide approvals in the mid-50s).
