So he can “cancel” the election, but only red states would listen. Blue states would still hold elections and report results. And with red states not holding elections, it’s safe to say any election would lean heavily left.

After midterms we’ll be able to see what’s gonna happen if that plays out.

But honestly, blue states should be prioritizing building up their own NG the next three years just in case.
