As was mentioned by Timmy, most of the people you are imagining in your head as "Orange County types" are just simply registered Republicans in a closed primary state.
Basically. Most Republicas I meet qualify their statements with "I'm a Republican except on insert social/environmental/healthcare/etc. issue here" while every Democrat I meet just says they're a Democrat/liberal/progressive and leave it at that.
To put it another way, for every single blue dog moderate Dem who lives here there's probably at least 5+ Rockefeller Republicans by comparison.
I don't think so I really think it Orange County flipped because of Mexicans and young people because Barry Goldwater even won Orange County by 10 points.
He was talking about how people are registered in the county and what primaries they vote in, so I'm not sure what the hell your post had to do with that, haha.
