Map if the NPV was reversed

[Neptunium]

The EC is unbalanced, yes.  Mainly because there are like 10 million more Dems than Republicans nationally and many are concentrated into big metro states like CA, IL, NY, MA, MD, WA, NJ. 

But Dems still have an EC advantage because despite their voters not being efficiently spread out, there are more of them and thus they have more safe electoral votes and there are definitely around 270+ electoral votes that at least lean Dem in a generic election.

Do you mean WI, MI and PA? I don't think so.
