Utah is the next best example and Salt Lake City and it's few liberal suburbs simply cannot overtake Utah, Davis, Weber, and Morgan counties. If Utah becomes blue, it'll be because the Mormon suburbs changed, not because Salt Lake City grew to a huge size.
I read somewhere that if only non-Mormons voted in UT, it would have given Clinton her biggest margin which makes sense. SLC is probably the only really good job market for young professionals in a really red state. Nashville is probably the only other good one.
