A breakup of The United States would be more complex than individual states going their own way. Urban vs rural vs suburbs, liberal regions vs conservative, etc. A large state like Texas with the resources to operate without Washington could pull it off, and could lead other like minded states with it. States where the divide between the democrat controlled cities and conservative hinterlands is greater would have a big problem going it alone.
Even Texas would have to wall off Austin, Houston, and plan on mass murder behind its lines. When people propose insurrection, you should know that is their intent.
You might see a race or a civil war between conservatives/liberals, but never a break up of the Nation. We have seen internal strife all through our history.
Subtle changes to the existing Constitution could be made and for the most adopted by the state, such as restricting votes by acreage and not individuals. Moreover, anyone on the government doll/payroll does not get to vote, or their vote is somehow weighted to account for that biased aspect. That’d eliminate the libtard bastions/cancers of big cities. So many Constitutional amendments to make to cure the cancer overtaking this country.
