Electoral College Reformation

I believe there is nothing wrong with the electoral college, I think it makes perfect sense, to have candidates battle in one state and when the candidate wins the state, he wins the electoral votes of the state. It is still controlled by popular vote. The difference is, the popular vote is divided into smaller groups based on geography and population, and the winner of these divisions wins the electoral vote. I see nothing wrong with that, and frankly, just having a popular vote would be chaotic, because there would be so much more room for error.
