Many of the arguments posted here for the electoral college are countered by Koza in the debate I posted earlier - in most cases there is data to the contrary. I strongly recommend watching it in its entirety, as many of these arguments - as well as many assumptions posted here about the underlying bases for the EC - are not well founded.
As for the argument that a popular vote would result in some states not having a voice, well, that’s certainly the case now (only it’s a different set of states).
