The Electoral College shouldn't be abolished because is working just fine, of course it's not perfect but gives power to people in States that a simple majority could leave outside. Just check, each State have two Senators, not taking in account how bigger or smaller they are.
Changing the rules each time we don't like could look great at the moment. Remember, it seems now a long since the Senate changed the so called 'nuclear option', I mean things could backfire.
