I guarantee you that any state that actually stands up and asserts its rights under the 10th Amendment will not be stopped from doing so by the federal government. What are the feds going to do -- send in the US military to forcibly subjugate that populace? I hardly think so.
Especially not with a state as large as Texas is.
Texas, or any other state for that matter, could easily force a capitulation on the part of Washington, if they simply refused to continue to do business in an unconstitutional manner.
Asserting states' rights under the 10th Amendment is the proper first gradient to re-establishing the proper constitutional role of the federal government.
Actually, it's the second gradient. The first gradient of passing 10th Amendment resolutions at the state level has already been done by several states. The next proper gradient is delivering a formal 10th Amendment declaration to the feds.
You may be correct. I think the US military will support Free America. But the feds will use the IRS and other agencies to quash it. In an case, it’s worth a shot to attempt a 10th Amendment move, even if it is 70 years late.
