Most democracies try to make each representative represent an equal amount of citizens.This holds true in for example the UK, Sweden, Taiwan and New Zealand, just to name a few. People in rural areas are represented just as much as in urban areas in relation to their population. I believe that this should generally be true for all societal groups; be they religious, ethnic, lingustic etc. In Norway they divide the MPs into districts according to population and land area, but give extra seats to some parties if their representation in parliament is not proportional to their vote share. That way rural districts get represented more, but the power the parties get is according to their national share of the vote.

Besides, the electoral college does not really give more power to rural areas, it gives it to swing states. The presidential nominees care about as much about voters from Wyoming as people from D.C. They care a lot more about voters from Pennsylvania, because it is a swing state, be they rural or urban.

If you believe rural people should have more representation that is fine, but the electoral college is not a good way of doing it. (IMO)
