Thanks.
One thing you might want to reconsider, though, is whether Texas would be the first state to go that way, as seems to be frequently assumed.
No idea, really.
I think it would have to be a state with a young population because one of the premises of the financial math of secession is that they would deport all the older folks on Medicare and SocSec. I can’t say that would work very well as a way to get elected to office in most states.
Utah, Idaho, and Texas are the “youngest” states.
