Man, these founder dudes were freaking brilliant! If you think we now have “fly over country” in the middle of the US, just imagine how bad it would be if we had a pure national majority vote. They would just camp out in NY and CA.
And the issue is much more than physical presence. If the candidates focus on the coasts, then they wind up talking about things that are important on the coasts. The concerns of fly-over country would be marginalized.
