The founding fathers established the electoral college as a compromise between electing the president in a vote by Congress and a popular vote. I would take an amendment to the constitution to get rid of it.
They established it as a way to launder slave votes into presidential elections, as stated explicitly by the man responsible, James madison:

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 the Negroes. The substitution of electors obviated this difficulty and seemed on the whole to be liable to fewest objections.
The electoral college exists because southerners were spoiled removed who wanted more power than they deserved, then they threw a tantrum when they lost anyway (the Civil War), now they keep threatening and whining if they can't keep their unfair advantage while gerrymandering to hell.
I'd be fine with the EC, if we also denied the electoral votes of states that don't follow the constitution or ratify all the amendments (Mississippi still refuses to ratify the 24th banning the poll tax).
