One purpose of the Electoral College is to prevent a limited number of pockets of dense population from determining the outcome of presidential elections. In that sense, it is a bit similar to the US Senate, and acts to give powers to the states as opposed to treating the country as one large electorate.
Without the Electoral College, the recent election would have been decided by heavily populated cities in the states of California and New York. With that in mind, voters could expect to see candidates spend the overwhelming majority of their time in geographical areas with dense populations, leaving those with sparse populations largely ignored.
Liberals chafe at the Electoral College for the same reason they are irritated by each state getting two senators regardless of population — it gives power to the states and recognizes them as significant political entities. It’s the same as the “states’ rights” argument which militates against a powerful national government. Hence, this is not a new argument at all, but one that goes back to the founding of our nation.
That liberals hate the Electoral College is illustrated by the comments of one Supreme Court justice. More on page two.

Another so called judge.
Well judge, there is something I would like to change, your employment
Her role as a member of the Supreme Court is to uphold the constitution and the law. She has no authority to make an amendment to the constitution. She should go back to sleep until she is needed.
Would one of those things to be your naptime?
She can not change a thing. Her job as a justice is to interpret the law and constitution not to make them. Time for retirement, demintia setting in.
she needs to go
Someone woke up the old lady
Look, ugly. Just go on and get the hell OUT!
Go back to sleep.
She is so old she has lost her mind.
