She made one error of note: Secession isn't strictly unconstitutional. A state may be allowed to secede, but the requirement is that the seceding state must be granted consent by the other states, per an 1869 SCOTUS ruling regarding Texas.
That said, there are no clear rules for doing so.
To be clear, she’s talking about the notion of "soft secession," not formal secession. It’s more like the difference between a cold war and an actual war—a slow, incremental shift rather than an outright break. I'm not holding my breath yet that the red states would be stupid enough yet to approve.
Oh, I get that's the gist, but she mentioned early on that secession (outside that context) was unconstitutional, and that rankled my historian-bones.
