The 3/5 compromise was a measure adopted when we had slavery so that the Southern slave states wouldn't be unreasonably represented.
OH no no no no no no
no. What a load of complete bullshit.
The Three-Fifths Compromise allowed the slave states to count 60% of their slaves as population --- without of course giving them a vote --- which
inflated their representational numbers so that they could
dominate via that artificial inflation. Don't you GET that?
Again this is simple math --- ADDING 60% of your non-voting slaves cannot on any planet be characterized as "limiting" anything. It doesn't "limit" anything but the power of other states who have to actually count their population LEGITIMATELY.
Far from "so that they wouldn't be unreasonably represented it
GUARANTEED they would be.
It has nothing to do with anything now because we don't have slavery anymore. I don't have a clue why you continue to insist on bringing it up.
It's a major part of the Electoral College's
function as designed. Maybe it's about time to wake up and smell the coffee. And it's the first of many examples of how the EC serves to
divide the country, which is what it's done consistently from its inception to this moment.
The bottom line is, the EC system is designed to prevent larger population states from steamrollering smaller state's interests.

Is that what they told you in Whitewased History class?
The reality is that it poured the power into the slaveholder interests and ensured that eight of the first nine Presidential administrations were headed by slaveholders from the South --- specifically from Virginia, the largest "population" state --- not really, but made so by the fake 3/5 Compromise numbers so that it had the most electoral votes --- so that it, Virginia, could steamroller smaller states' interests.
Which they did. Know how long this country dragged on without addressing the elephant-in-the-room question of slavery, hanging on while other nations in Europe and the Americas were reforming themselves?
Does it ever occur to you in reading the list of Presidents that "Virginia" keeps coming up? Ever wonder why? It's not an accident; it was engineered that way. And leading to the next point below, the only break in the Virginia domination of this country's first four decades was the single term of John Adams of Massachusetts; it was when that happened that the power-hungry adopted the "winner-take-all" system so that Virginia's already-inflated EV could be weighted more in its favor. And it worked, as Virginians then took back the White House for another 24 straight years.
There, my lad, is your "larger state steamrolling smaller states' (and regions') interests. And doing so via the artificial bullshit population numbers that allowed it with a wink to dominate----- the Electoral College.
I like having States and I like having the EC and the system we have. IF you want to talk about changes from winner-take-all to proportional electors, that's fine... I don't have a problem with that conversation.
That is the first and foremost glaring issue, and it has always been my starting point. The idea of any state telling Congress that "it's unanimous, everybody in our state voted for candidate X" is absurd on its face. And as I've described that dynamic (a) renders irrelevant the vote of every voter in a "locked" state whether they agree or disagree with their own state's plurality; it (b) creates artificial and entirely bullshit division concepts of "red" and "blue" states; it (c) restricts candidates to so-called "battleground" states and ensures that most Americans will never even see them; it (d) makes us all dependent on polls to find out whether it's even worth getting out of bed on Election Day; and it (e) perpetuates and protects the Duopoly of two lookalike parties both of which have been around way too long and no longer stand for anything except the self-perpetuation of their own power and the Duopoly on which it stands, one nation, divisible, with color-codes and bullshit division-category terms for all.
"Electoral College" is in effect the opposite of "E Pluribus Unum" It's time we wake up to that fact. Even if it means ---- horrors ---- actually questioning the history books we were served as children.
