My arguments are elsewhere in the thread. Go read them.
Obvious examples of this are ending slavery and the votes for people other than white land owners. These are positive moves on the part of our government over the years.
To me, the easiest thing to do is put it to a vote. Call for a constitutional convention, address the issue, and see what the general population wants to do. Should it become apparent that the electoral college is deemed unnecessary, then so be it.
I have read Madison's Journal as well as a book (cannot remember the author), "Miracle in Philadelphia." Sherman and others were concerned that the general public would not know enough about the candidates to make an informed decision. Why? Because it often took news weeks and months to travel from one end of the country to the other. Hence we have the Battle of New Orleans bein fought after the end of the War of 1812 because Gen. Andrew Jackson had not heard that the war had ended.
Modern communications methods have eliminated that concern.
