As for the cities, they are all run by democrats, Houston has a gay woman mayor, 2/3 of dallas city council and 90 of county supervisors are democrats. Ft Worth is more conservative, but is a little more "good ol boy." Towns like Temple or Tyler are much more conservative, lower cost of living and generally fit some of your desires. The both have community colleges and enough entertainment you won't feel left in a wasteland. BTW if you want sports better stay closer to DFW or Houston - both with plenty of pro teams.
Our avg. summer temps hover at 105*. Our avg. winter temp. is about 25*. Considering the political landscape we’re facing, and have had to deal with, the trade-off would be worth it.
