Yeah seriously the district is more suburban bay area than it seems. Brentwood, Tracy,Mountain house are all suburban and will probably vote similar to the tri-valley region. Andal was probably selected by the crazies that are all over the place in the valley. Even the exurbs of the bay area are not that extreme. If the republicans were smart they would pick some GOP moderate from the suburbs. Anyways Andal cant swim against the wave that is coming for the GOP.
I'm surprised they can't win this one. Pombo almost held onto his seat, so any other Republican should be able to take it. But it is not to be.
To reiterate earlier comments, it's safe to say that CA-11 is trending left. As long as McNerney doesn't alienate the more rural parts of this district, he'll be pretty safe till redistricting*.
*Of course, he could be a victim in 2010 if Obama become President.
