Only democrats want the EC abolished. Think President Cankles. And think about President DeBlasio or President Ocasio-Cortez in 2024.
I see the EC as one of our defenses against tyranny. OTOH, I see the two party system in its current form as a force for tyranny.
I'm willing to listen to the guy's argument. In the end I may reject it, but at least I'll know what I'm rejecting.
