D) Sure, many states get ignored, but it might be better if a candidate spends more time in Florida than Kansas. Also, how would candidates know where to campaign with no Electoral College?
More states would get ignored under a straight popular vote. Both sides would just rally their respective population centers in that case. With the EV, any competitive state could be the difference in a close election.
Question to the pro-EC voices: if it's such a good system, why do no other countries use it? Why do no states use state-level versions of it?
That's an irrelevant question to me. A lot of countries or just a few countries having a certain policy doesn't make the policy good or bad. That's just argument ad populi.
