I think this elector system is a nice little legal fiction in this date and age. I wish it weren’t so, but despite the statements to the contrary on this forum, none of us voted for electors on the ballot. We don’t even know or care who they are.
Doesn't matter, they are real people, and they cast real votes, which really decide who becomes President and Vice President.
Besides, in some states their names are on the ballot. I'm pretty sure it was that way in the first few Presidential elections I voted in, back in the dark ages, when we used quill pens to circle the names of those we were voting for, or written in names as required.
Actually my first Presidential election, in '72, I used the old mechanical "lever and counter" machine. In '76 it was the paper ballot, circle the names deal. I've also used a punch card, with out the punching device, although they did thoughtfully include a paper clip for that purpose with my military absentee ballot. I've used two different sorts of mark-sense/color the circle type ballots, including this year. I've also used electronic voting machines in '00 and '04.
