Apparently, 18% of the inhabitants of Texas want to secede from the United States. Other than opening the door for other states to follow, which I’m sure, even if voters reached a majority the federal government would quash in no uncertain terms.
But let’s look a the consequences of such a move; should it be allowed to take place, and indeed passes. Texas has no personal income tax, but it does impose 60 other taxes ranging from tobacco to retaliatory taxes. Texas would lose any tax money it receives from the federal government, so the imposition of higher taxes to pay for basic infrastructure would surly follow such a move. They could also require any visitors to obtain travel visas, and the federal government could impose the same on anybody leaving the state. I could go on and on, but it seems to me any state wanting to secede from the union would be creating more problems than the ones they are trying to get away from.
