Because of high dense population democrat crap holes like LA, NYC, Chicago, etc. The EC was set up so the most idiotic and stupid of voters won't always screw up the Presidency.
The EC is a participation trophy for the Repugs-
It doesnt matter what city/state- it is who gets the most votes nation wide.
Are you a make a wish kid?
When three wolves and two sheep vote on what's for dinner, the sheep are going to be disappointed. Every time. That's why the system is set up the way it is.
