It's important to consider the intent of the founders. It wasn't to avoid a popular vote for president, it was to avoid the people deciding altogether. The government is a represenative system where the people elect those supposedly more studied and thus better suited to make the best decisions on their behalf.
The decision for president is no different. The electoral college is essentially a temporarrily elected independent House and Senate type group, whose sole purpose is to get together and select the best qualified person for president, regardless of party, special interest, or other affiliation.
That is not at all the system in place now. The founders would be mortified by what it's become.
