The small-state bias in the Electoral College is NOT what accounts for Mr. Trump's victory despite massively losing the national popular vote. What accounts for his victory is that (arguably unconstitutionally) almost all states assign ALL their EC votes to the popular vote winner in their particular state, thus disenfranchising the minority in each state. 

If that simple problem were corrected -- which could be done without amendment to the Constitution -- we would have a much more fair result, with the EC result more closely matching the national popular vote, while yet preserving the small-state advantage. The solution is for each state -- all states -- to assign their EC votes proportionally to the popular votes in their state.
