Thinking about this...
The idea of the Union (States' Rights) offered the People to freedom to live as they choose with mutual (limited and voluntary) economic and security cooperation. This was a good plan IMHO. But they certainly didn't envision a Union where one man's election as president determines which doctor you can see, how much of your paycheck you can keep, or even if you have a fundamental right to defend yourself.
And it's interesting the see the consequences of the CW. Once secession was off the table how did FedGov behave? Did they continue to respect the states and the People or start to seize as much power as they could (Federal Reserve, Income Taxes, Prohibition, etc...)? That trend has continued, non-stop, and obliterated nearly restraint imposed by the Constitution. Look at how USSC cases are decided. When was the last time the court said to FedGov "you have no charter here?" Not in my lifetime.
So it would seem the CW was a lot more than just a referendum on secession but really on States' Right absent a Constitutional Amendment that would have legitimized Federalism on steroids.
It's gone off the rails and even with Trump's election, this system isn't fixing itself. Look at the protests happening yesterday and today. We aren't one America anymore. Looking at the EC map, we aren't even one state in most states (urban vs rural).
So why shouldn't Libs be able to live as they please and Conservatives as well? Why are 320 MILLION people forced to live under one government that decides all by a slim majority of voters? Face it, we "won" this time via the EC but demographics are destiny and the folks coming here are brining their values with them (assimilation is racist!!!).
