The "consider the politics" discussion has some merit on both sides. On the one hand, most places you go if you're decent to others they'll probably be decent to you. Of course there are exceptions here and there, but that's got to cover 90% or so of America, and probably the same world-wide.
On the other hand, politics aren't just a social club, they do have real world consequences. So if the political decisions being made in a location -- taxes, school funding, infrastructure spending, school curriculum, access to abortion, etc. on the local and state level, plus whatever the US Congressmen and Senators are up to -- are going to bother you, it makes sense to take that into consideration before moving. Moreover, different places have different cultures about how and whether politics are discussed (along with religion and a host of other "sensitive" topics). So if you don't mind having neighbors with different political points of view, you might still be turned off if your new city or town is littered with yard signs and everyone talks politics and church all of the time.
I have no idea what the "politics/religion/etc. talk" culture is in Texas. Given that it's so big, there are probably several different ones. But it's one more thing to consider when you're visiting, along with the hundred other things you'd consider before moving across the country.
PS: Politics aside, why has no one mention the weather yet? Aren't the summers brutally hot and humid?
