You're missing one point and that is federal taxation hits us all equally. I live in California and my EC vote is 1/3 of that of someone in N. Dakota... How is that fair? I would argue that unequal taxation representation is a flaw that a simple vote remedies. Unless of course if the feds are going to give a 2/3 tax rate reduction to compensate me for only having a 1/3 vote... I'd go for that...

Precisely. I live in California and I've NEVER liked the EC (no matter who has won...). Why should my vote count 1/3 as much as someone in North Dakota or Idaho? Since voting for a given President could have a direct impact on my level of taxation (rate), why should I only have 1/3 as much representation (vote) as someone in North Dakota? It's taxation without fair representation, plain and simple.
