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.
Not the full picture. If you look at the precinct maps you'll see that college educated white areas were just as likely to swing against Trump as Hispanic areas. CA-48 voted 17 points for its GOP representative to congress but 2 points for Hillary Clinton for example.
Trump is a GOD AWFUL fit for suburban Orange County Republicans. I'm not sure you could make a worse GOP candidate to cater to this group.
Now that's something I do agree with now what I really wonder is what would have happened if Ted Cruz had been nominated would we have seen the yuge swings in northern Virginia, southern Connecticut, Atlanta area, Austin area,Dallas area, and socal
