if the facts were such that only one or a small handful of states could give the election to a candidate, perhaps you have a some argument
but that's not the case nor has been the case in our history and has to date always worked to give small states at least some voice as states
in 2012 the state with the most electors, I think, was California with 55
270 is required to win the presidency
trying to cobble together 270 electoral votes is the key
granted there is not some equal electioneering going on in all states, never has been, never will be
but small states at least have some say. the idea of the electoral college is the protection of and the preservation of individual states
they, the small states, wouldn't have any input without the electoral college
without an electoral college, if you had the option to visit new york city, with say 10 million people in a a 200 mile circumference, or drive around Wyoming looking for a vote, where would you spend time?
I am not saying the same effort is ever spent in a small state as in a large one, but with the electoral college system the votes cast in a small state have a collective voice as a state
if you don't think having states is appropriate, and that states have no useful function today , nor should be allowed to have their own local and state laws and governance and freedoms or lack thereof, and input into our system as INDIVIDUAL STATES, then that's one thing, but I think preserving the states are worthwhile, and of course we just need to follow the 10th amendment as well
