It seems fundamentally fraudulent to do that. It makes it look like the popular vote actually matters in a presidential election. It's really a bunch of people you have never heard of, voting the way they were told to vote, while under threat of party excommunication if they reneg. There's more democracy to it whenever the Catholic cardinals elect a new monarch-for-life.
The original idea, to send representatives of the community in good standing to make their own decisions in the best interests of those communities, was well-intentioned. It isn't the modern elector's fault that their role has been nullified and obviated by political undermining.
