Definitely didn't in California, though it was likely a 4-6 point loss as opposed to the 10 point loss the exit poll said.
It may have actually been a 10% loss. Looking at precinct results, the lack of an overall GOP swing in California was almost entirely thanks to Asians.
Vietnamese certainly swung to Obama but not sure about others. Looking at precinct results in the San Gabriel valley, things didnt change much. Whites did swing back, and all of the swing away from Obama can be explained by that. Still, according to exit polls in 2008, Obama actually won whites by 6 points. Even if it was more like a 2 point win, a 6 point swing back would imply a 4 point win for Romney. It also depends on if 28% of the electorate was 18-29 years old. I don't really buy that.
