So, by personal reasons you mean you're afraid of Democrats?
I like the PNW, and Rockies. Portland and Seattle are both excellent bike commute cities. They aren't great places if you're trying to avoid Democrats, however. Maybe try Boulder. I've been there once on a skiing trip so I don't know a lot about it. Clean air, mountains, environmental conscious, physically active... not much to not like if you ask me. Or look at something like League of American Bicyclists.
Davis, Portland, and Boulder are "platinum". Again, not much I know about Boulder, but Davis is great for bicycle commuting, superb schools, conservative for California (more so than Portland or Seattle), well-educated, family friendly. If you like long, hot, dry summers, mild winters, and can put up with it being on the quite, side it's pretty nice.
