And all this is why we're governed now by a minority government much further to the right of an already right-leaning population.
People in urban areas don't have the same influence with their vote, which combined with gerrymandered districts can make it look to them as if voting won't do much.
The pattern with most American cities is very predictable - an urban core that used to be poor but is now gentrified and expensive if the economy is good, patches of older suburbs near the core that tend to be lower income to middle class, and an outer exurbia (often outside the ring road, a freeway circling the city) that has most of the new job growth, the upper middle class, and the Republican voters.
Since cities like Houston, Dallas and Phoenix are being built on flat ground they follow this pattern closely, and if you are new in town, you can predict where you can find things based on it.
Rural economies are anything outside the exurbia and for years have had little job growth, if any, and outmigration. This concentrates the retired voters who are the base.
It also makes the party conflict a generational war between a home-owning older Republican voter and a young voter who has migrated away from home in search of work or education and has few assets.
I have the impression migration is less in Europe? Regions would then mean more. Here many, many middle class people live far from their parents, although that has been slowing down as real wages stagnate.
So you can pretty much predict how a neighborhood will vote if you know its racial composition and its average age, with the exception being hard core religious areas.
If I want to find liberal Dems, I look for a suburb near a university. If I want to find conservative Republicans, I head out of town. We don't have many cities with strong local personalities. There are some: for example, Salt Lake City, Philadelphia, San Antonio - but if you're looking at a liberal enclave, it's going to be pretty similar anywhere you find it.
This is part of the Republican dilemma - sensible conservatives being outnumbered by pockets of the hyper religious and the elderly. And the problem with the Democrats is the tension between multigenerational minority urban neighborhoods and nomadic, middle and upper middle class voters mostly in their own enclaves either in exurbia or the expensive gentrified core.
This situation is neatly set up to disenfranchise younger voters who lack wealth.
