This [1] is population/EC vote rather than EC vote/population, and it's slightly out of order, but it's a steady slope. There's nothing like a normal distribution for people/EC vote ratio. There's just a large range between the power of a California voter and the power of a Wyoming voter. I think this graph shows just how ridiculous this is, Rhode Island voters being inexplicably much less powerful than Connecticut voters, when arguably they're all the same metro with either Boston or NYC, and would thus count as getting just as many "visits" if candidates only visited big population hubs.
