I don't think this is a valid reason to continue with the electoral college - but it might be a good reason to slowly dissolve the concept of states and instead let local and national politics interact directly - the state level is where the needs of different localities are being erased more than the national level.

Local politicians should be concerned with their locality - national politicians should be concerned with the nation and making sure that no localities are presented with problems beyond the scope of their power... the state sorta does both - but it also serves to mask local issues within the state's representation up to the national level. It's why I'm rather fond of the house and less fond of the senate - as a former Vermonter I had intensely good representation at the national level - I had one house rep and two senators which were concerned with representing me specifically - but when I resided in MA our rep was concerned with local issues but the Senators were more focused on pushing forth agendas that the state-house was pushing out... so the representation of individual localities were lost on those senators.
