Aurora and Littleton are middle class suburbs of Denver. Aren’t those like suburbs of any major city in America?
Almost, but they do lean further to the left. Their “conservatism” is a far cry from the conservatism of some of the Midwestern and southern states (exceptions being states like Florida, with large influxes from the northeast and left coast).
Colorado has been filling with people from the northeast and west coast for generations. I’ve found that while not absolute, people with more generations of Americans behind them are more likely to be good neighbors.
