Not all the Hispanics in Texas are democrats. Many of those that are would leave if it were an independent nation.
The real issue is could Texas defend it’s Northern border as well as the Southern Border?
I’d rather have Mexicans than Yankees or Californians
Again, you guys need to make up your mind. The guy above just claimed he wanted the opposite if Texas became an independent nation.
Personally I think you'll get your wish that Texas will "secede", but not in the manner you intended. In a few decades you'll be living in the Spanish speaking Republic of Aztlán.
