Not sure how this myth continues, probably because it usually goes ignorantly unchallenged. First of all, there are no "flag laws.” There is a flag
code, but you can’t be penalized for not following it. Furthermore, any state flag can be flown at the same height as the US flag. But Texas’ own state flag code says, “the United States flag should be above the state flag.”
Sec. 3100.055. DISPLAY ON FLAGPOLE OR FLAGSTAFF WITH FLAG OF UNITED STATES. (a) If it is necessary for the state flag and the flag of the United States to be displayed on the same flagpole or flagstaff, the United States flag should be above the state flag.
Another myth. The 1845 US Joint Resolution for Annexing Texas floated the possibility of additional states “not exceeding four in number, in addition to said State of Texas.” But the US Constitution (among other sources) overrides this prospect. In Article IV, Section 3, it reads “no new states shall be formed or erected within the jurisdiction of any other states.” Reconstruction after the Civil War further clarified this and also "right to secession" never existed anyway. It's not anywhere in any Texas founding document, and it does not exist in the annexation agreement either.
Our state legislature can do just what California's recently did, this does not mean it passes muster in the US Federal courts and also does not mean it will actually happen. Article 4 section 3 completely nixes it, so short of a US Constitutional Amendment they're out of luck dividing into three or any other number. And so are we.That's quite subjective. It's dog-ugly there IMO, certainly compared to the Llano Estacado which by the way is home to the 2nd largest canyon in the US. A super great big hole in the middle of the table rock!
