Civil War-again?

But if that's the standard, there's no defense if a Democratic president uses the same federal power in ways conservatives hate. At that point, the disagreement isn’t about constitutional order at all—it’s about tribal loyalty.

There isn’t. If a Democrat (or Republican) decides to force something on me, I am powerless to stop it. Like banning me from having a job unless I got vaccinated.

My state can’t resist such things. Didn’t work in 1861. Didn’t work in the 1950s/1960s.

And no matter who the president is, most Americans lose.

Would you like to repeal what happened in the 50s/60s?

The federal government has absolute supremacy over immigration enforcement.

The federal government has absolute supremacy over immigration enforcement.

Minnesota, California, Maine, Oregon, and other states are following the law, but they are being threatened and intimidated with a military-style occupation. There is no Supreme Court case against these states. There is no armed uprising against the federal government.

States cannot set their own immigration policy, legalize or deport non-citizens, or override federal immigration law. But they are not doing these things. Sanctuary cities may be frustrating to the federal government, but they are operating completely within the law.

That's quite different from the times you mention.

1861 (Fort Sumter / Civil War)
This was an organized secession backed by state governments using military force. It’s the clearest case of states attempting to nullify federal authority by war. It failed, decisively. None of the states are doing anything like that.

1950s–60s (Little Rock, civil rights enforcement)
Here the federal government enforced constitutional rights against states that were openly defying Supreme Court rulings. That's not happening either.

Detroit (1967)
Michigan’s governor formally requested federal troops.

Los Angeles (1992, Rodney King)
California’s governor requested federal assistance.

Interesting how federal agents trying to detain an armed man who was attempting to block a striking a federal vehicle isn’t an “armed uprising”.
