Electoral College workaround already underway. Eliminating the Electoral College does not even require a constitutional amendment. An effort known as The National Popular Vote Interstate Compact is an agreement among numerous U.S. states and the District of Columbia to award all their respective electoral votes to whichever presidential candidate wins the overall popular vote in those states. Once states totaling 270 electoral votes join the compact–which only requires passing state laws– then the next presidential election will be determined the the popular vote, not the Electoral College.
As of November 9, 2016, ten states and the District of Columbia have signed the compact, totaling 165 electoral votes. So, we are already over 60% of the way there. Pending in PA and WI for another 36 EC votes if adopted by those states.
