The district includes more Republican areas like Corona and San Clemente, it was gerrymandered to be safe for Calvert, so it really is quite Republican. I think come redistricting, the district will end up getting smaller and actually improve Democratic chances here.
Yeah, it covers swing territory in Riverside county and some Heavily Republican parts of Orange county. But Riverside (from what I know) has a considerable Hispanic Democratic base, and if PPP's right here (which given that it's a individual CD poll with maybe 100 Hispanic respondents, might not be) it kind of throws a wrench in the whole "Hispanics are a forever Democratic voting bloc" meme. Democrats should be getting at least 66% of the Hispanic vote here.
Granted that Boxer is doing much better with them than The Congressional candidate, but this suggests there signs of life for the Republican party
