"I think Texas is the primary target because Arizona and New Mexico were essentially ceded some time ago because of their lack of private land ownership. All the Feds had to do was walk off their own land which they did some time ago. California politically capitulated some time ago but then there is that pesky Texas with it's highest in the nation rate of private land ownership and rainy day fund that allows us to thumb our nose at Uncle Sugar when he gets a bit too froward."
Yes, and even though a huge percentage of Texans now live in the six or so larger cities, and Texas has a recent history of immigrants coming in from many other states, even California, there is always that history lurking in our memories, especially those born and raised in Texas. And now Texas not only has size but is the second most populated state.
Some people who went through the U.S. public education system after it got taken over by Transformational Marxism beginning in the fifties but really getting going in the late sixties, don't even know that Texas was an independent country, and there were English and French embassies in Austin.
So, when Texas begins to act like an independent country and tries to seal its southern border, that reminds us of our history.
