well, it’s the place where BYU lives. And the most liberal is Detroit, Michigan. All kinds of interesting things to note: all of the northern Californian cities are liberal (I grew up there) and most of the conservative Californian cities are in Southern California. One of the most conservative cities is Hialeah, Florida, which is next to Miami, where I currently live, and filled with conservative Cubans. I was unable to find on this site how liberal and conservative are determined (I’m guessing voting patterns), but I don’t know if it was judged just on national elections or if local issues were considered. It is worth pointing out that there are some issues that are not that easily categorized, so don’t overestimate the accuracy of this study. Just interesting reading for the geographically minded.
