With all due respect, Reg, I think that's a bit of a hasty conclusion.  I've lived in Texas for 20 years, am NOT a Republican, but can both see and respect the good aspects of living here.  Aside from the recent issue, infrastructure tends be pretty good.  Our local public school is good, too.  People are quite friendly and helpful to one another, and as a rule of thumb, cost of living is better-controlled than in some obvious Democrat-run states.  

That said, the current power issue (note that I never did lose power), is a good case in point of what happens when minimum standards aren't rigidly enforced.   It is not, however, and indication of lack of investment in the infrastructure.  It's more an indication of lack of investment in maintenance costs, which is similar but a bit different.  

Unlike Florida, I would not say that the Texas response to COVID was poor.  Densely-populated areas were hit fairly hard, but Texas never saw (yet) the kind of spikes that were seen in New York, New Jersey, Massachusetts, Illinois, Arizona, and California.  Tests were available early on and almost always for free at drive-up centers.  This was much unlike the situation in my parents' state of Oregon.  Roll out of vaccines has also been faster here and was the subject of several write-ups in praise of it in national publications (and not just conservative ones).

I don't mean this be a full-on defense, but having lived in four US states plus several years overseas, I am pretty confident concluding that it is nowhere near as obvious as you are trying to make it.

All that said, the sort of smug, morally superior attitude that comes off many Texas conservatives is just nauseating.  It's a weak spot in their armor.
