Wow, those are huge swings towards Obama in the Vietnamese areas. Most of them were 55-60% McCain, now in some areas as much as 60% Obama. McCain probably overperformed in 2008, but this has to be by far the best Democratic performance with Vietnamese voters since before the Vietnam War.

Where were the biggest swings against Obama?

Looks like the wealthy southeast of the county (Laguna Niguel, San Juan Capistrano, Mission Viejo) had the biggest Romney swings, though there were some big swings around Yorba Linda, too. Generally looks like the poorer/less wealthy areas swung Obama while the rich areas swung Romney, with only a few exceptions. Actually surprisingly close to the sort of swings we thought would happen this election, even though nationally it doesn't seem that Romney overperformed in wealthy areas the way he was expected to.
