Cities do have a tendency to attract, or maybe produce, liberals.
It would be interesting to find out the relationship between liberal mentality and attraction to living in cities, IOW, which one causes which and why.
I hate cities. I appreciate the services that can be available, especially as far as medical options, but otherwise do not see the attraction.
OTOH, cities also have the tendency to either drive conservatives out or cause them to not go there in the first place, leaving even more power in the hands of the liberals. That's why I have a sympathy deficit for any problems they bring upon themselves.
