This was the very polite version of Texas saying cram it up your cram hole. Now if we don't win in November and repeal Obama care we might hear a less polite version of that message.
It might go something like this. Obama care STOPS at the border of Texas. Accept this kindly or we might just deal with you the same way we deal with a foolish batter that charges the mound.
Unfortunately, Texas in the only state with authority to do all of this. The Republic of Texas, a soverign nation, joined the Union with a treaty. It was the only state to do so. The treaty says that it can also leave if it wants to.
