Those voters who pay more in federal taxes, have a diminished vote because of the college. Blue states kick ass over red states in taxable income. The economic engines within each state vote blue.
However, the US Constitution was written to protect the little guy, to not simply favor the popular or economic majority. Hence, the EC forces a President to answer to all pockets of the nation - urban/rural and across the cultural divides.
So, it remains important for a candidate to win each State, and let the voters of each State decide who they want for President.
All of this requires a fair and accurate census. We know that Republicans want to rig that process as well in the same manner Republican state legislatures rig the gerrymandering and suppress votes. So, when Baron and Ned pontificate about fairness, feel free to barf.
