Texas was an independent nation in the 1830s-40s, though the old cotton-based Republic of Texas was pretty much a failure. Texians were only too happy to become a part of the United States.
Nowadays with its oil and gas riches, efficient agriculture and independent electric grid, Texas is a lot more capable of independence. And state government has worked at making and keeping it so—just in case.
“Generally speaking, we have made great progress in becoming an independent nation, an ‘island nation’ if you will, and I think we want to continue down that path so that if the rest of the country falls apart, Texas can operate as a stand-alone entity with energy, food, water and roads as if we were a closed-loop system.”
Water could be the biggest problem, but desalinization of the Gulf would be a possibility, if a high-priced one. Naturally, these remarks by Railroad Commissioner Barry Smitherman, have been twisted by the usual leftists to suit their politics. But that’s no big whoop.
Via The Blaze.
UPDATE: More nonsense, this time from the right. To these people Texas is no more than a stereotype. They need to pull their heads out of their posteriors.
THE TEXAS SCRIBBLER 
Then wouldn’t Texas have to fight off amorous advances of Mexico to join it as another province or what they call it there?
Not as long as Texas continues to act as Mexico’s pressure valve, taking in its poor who might otherwise undermine the rich by fomenting revolution in Olde Mexico.
