Voter fraud still exists in the popular vote. Also, may I remind you that the percentage of people who vote in this country is barely fifty percent. This means that half of the country is not even represented by the popular vote. Then, of this fifty percent of voters, a majority of them do not vote based on real issues. I am telling you that in this land of great democracy the people, as a whole, do not always understand what is best for the nation.
People always vote based on self-interest.
What issues affect a northern business owner does not affect a southern farmer. This is what the Electoral College does for America. It takes the popular vote into consideration but ultimately makes decisions that the average American, who has not immersed himself in politics, is unable to make. Also, if the popular vote was all that was needed the minority vote would be completely ignored. The candidates wouldn't waste time encouraging people to come out and vote.
