That's an interesting hypothetical, but it's not, by and large, how Americans understand the Electoral College :)
More seriously, I agree with you. As I said below, I have no ideological opposition to adjusting the levers of the EC (or even replacing it with some other system that more explicitly defines its goals within a modern framework), so long as that system is not based on a simple popular vote (which I do oppose).
No, you can understand dual sovereignty, and support it and the separate powers of federal and state government, and still prefer both sovereignties be based on equal representation and democratic norms within their respective scopes.
