If at first you don't secede, try, try again.
There's just one small problem with this: the belief that Texas is the only state in the Union who has the right to secede in it's state Constitution is a MYTH.
What the truth is: Texas has wording in it's Constitution that sort of 'mimics' the Declaration of Independence as such:
"All poitical power is inherent in the people...they have at all times the inalienable right to alter their government in such manner as they think proper."
Now...that doesn't mean that it's a dead issue...
