Look at the history of compromise that lead to the Electoral College -
Madison acknowledged that while a popular vote would be ideal, it would be difficult to get consensus on the proposal given the prevalence of slavery in the South:
There was one difficulty however of a serious nature attending an immediate choice by the people. The right of suffrage was much more diffusive in the Northern than the Southern States; and the latter could have no influence in the election on the score of Negroes. The substitution of electors obviated this difficulty and seemed on the whole to be liable to the fewest objections.
