This person knows just enough to sound credible and still get it wrong. He says that the electoral college requires states to allocate all delegates to the popular vote winner in each state, which is not true. States can allocate delegates however they want, and at least two states allocate proportionally to how how their populace voted.
This is a critical difference, because eliminating a mismatch between the electoral college and national popular vote doesn't require eliminating the college. Eliminating the college requires a constitutional amendment, which is difficult to achieve. The National Popular Vote Compact requires nearly as much effort, and it's incredibly fragile, because as soon as a few states allocate all of their electors to a candidate who lost in that state, they'll pull out and the whole thing will crumble.
The solution is for states to allocate delegates proportionally. That is in the best interest of each state, so it's not fragile. It can be accomplished one state at a time, so it's logistically easier. It doesn't require huge buy in to work, just a handful of states, so it's easier to achieve and more stable. Every mismatch better the electoral college and national popular vote in US history would not have occurred if states allocated delegates proportionally, so it solves the problem. People should start recognizing the real problem, so that we can work on a real solution.
