It will take a catastroph of epic proportions to give Dems enough seats in both chambers to amend constitution and get rid of electoral college. Do not see this happening anytime soon. And truly hope it will never does. On the other hand is it fare that 2 senators from a state with a million population have the same weight as the one with more than 10??? But that is what the law says!
That's why the founding fathers balanced the Senate out with the House which elects the number of reps based on population of a state.
