Texas has swarms of stupid people, but my guess is that you just saw this only online and thought it was clever.
The time for the stupid Texans to get really stupid about the 2016 election has not yet arrived. Presently, I imagine they are using their stupidity in other ways, like discussing sports.
Not all Texans are stupid, but those that are, are as easy to identify as Moe, Shemp, Larry and Curly Joe were.
