The ERA had an expiration date built into it.
That expiration date has passed.
So it is unlikely to become part of the Constitution even if Virginia passes it.
It's dead. Any belated ratifications are strictly a case of virtue signaling, and the Archivist of the United States will return the Certificate of Ratification to the Secretary of State of Virginia with a rejection letter attached.
The left will declare it “passed” if another state “ratifies” and leftist judges will act as if it is a duly ratified amendment to the Constitution. And we really don’t know what the USSC will say. We can assume that Roberts will vote for it and maybe Kavanaugh, too.
