Poll from Public Policy Institute of California (Likely Voters).

Donelley 10%
Blount 2%
Kashkari 2%
Other 3%
Undecided 36%
Interesting. Looks like Brown and Donelley are the only ones with name ID at this point, so a Brown vs. Donelley run-off is certainly possible if Donelley plays his cards right.
I find it amusing that the favorite of the liberal media/GOP establishment, uber-RINO Kashkari is essentially polling nothing at this point. (I never heard of him before he announced for Governor either, but once I found out he was the guy in charge of TARP I immediately ruled him out).
You could probably pick a random name out of a phone book like “Wojtowicz” and 2% of voters would select it as their candidate.
