Arguably, one can say that the electoral college decouples electing the head of state from possible corruption from an entrenched parliament while reaping the benefits [?] of not having them elected by the people directly. Realistically it means nothing, especially when states mandate that all of their electors vote for one candidate.
What I really don't about the EC is that policy becomes dictated by less than a dozen "swing states". Who cares about Massachusetts or Mississippi when Ohio and Florida are angry about something?
