Technically speaking, it's perfectly constitutional for some of these states to do what they've been doing to get around the electoral college.
The problem is that what they are doing is the polar opposite of the original intent.
That, of course, begs the question of the original intentitself given that the founders truly were aware of the power and tools they left for the states. The states are the ultimate republics which have full power and authority overlooking the federal republic.
A lot of times we hear the term constitutional republic quoted as our form of government. That's not technivally correct. We're a compound republic. Meaning, again, each state is a republic in itself with full powers granted to it over the limited power of the federal republic.
I'd have likely been an anti-federalist had I been alive back then to be honest. They've been proven correct in their predictions time and time and time again.The constitution really is kind of designed to empower tyrants.
