Racialized voting patterns in Riverside Co, CA?

Also most of the Hispanics are white.

Is the proportion significantly different from Los Angeles County or the state at large?

And to answer the question, Whites in these areas are pretty Republican and the Hispanics are sort of swing voters. They usually end up voting Democrat, but look at how they vote on propositions. And I'm not talking just about social issues..... Definitely the sort of place Republicans will do very well  in when it's their year.

The old 46th contained a lot of the Democratic areas of Orange County. The only really Republican area in that district would be Garden Grove and I can't tell if it sticks into Irvine, but if it dd then that portion of the district. The rest is heavily Hispanic today and must have had a lot of Hispanics in the mid-90s as well. Not as many, sure, but it's not as if there are that many Hispanics in Riverside County today either.

Also I'm sure it helped that Sanchez's opponent was Bob Dornan. A better candidate might have survived a few more cycles.

i was playing around on Dave's Redistricting App. The precincts in Riverside County that are majority white gave McCain 56 percent of the vote. The precincts in Riverside County that are not majority white gave Obama 58 percent of the vote. So there's obviously a difference, but compared to the country as a whole I would say it isn't all that polarized, especially compared to parts of the south.

It's definitely not polarized based on race solely. The whites just happen to be very Republican, like in neighboring Orange County and San Bernadino County (which has almost the exact same racial demographics as LA County), and the Hispanics sometimes vote Republican.
