The Lie

Just to make 100% sure everyone gets it - the alternating capital letters implies mockery. That was the 1910 election and clearly the south voted Democrat and the north voted Republican.

Don't even start on the fact that, if it weren't for the electoral college and the 3/5 compromise, slavery would have never ended.

Explain

The south knew that counting slaves as part of the population, albeit a segment unable to vote, would have given them significant power advantages.

This isn't a hard concept. These limitations prevented that

Without the 3/8 compromise we wouldn't have had a country. If we did, house and electoral college representation would have either included all slaves or no slaves (since they weren't citizens). Actually without the electoral college, the 3/8 compromise would have given the South less power in presidial elections since slaves weren't actually voting. So worst case, slaves count fully for house representation, and not at all for president.

I don't actually know what the population numbers were or how it would have gone without the 3/8 compromise, but that's speculative fiction.

Population was used to determine representation, not just voting population. So a slave owner would have been vastly more "represented" with slaves being fully counted.

Public Ed has intentionally twisted the 3/5 into "OMG BLACKS WERE SEEN AS LESSER BEINGS!" Not so. Not so.

The Senate representation had nothing to do with population. House does, and with no compromise and assuming the lack of compromise went the South's way, they would have been overrepresented there.

With a popular vote instead of the electoral college, inclusion of slaves in calculations would only affect the presidential election if they actually voted, which wasn't ever on the table.

Please tell me how I'm wrong.

You think that people who were bought and sold, whose children were also property weren't seen as less? They were livestock, except when it benefited those States to count them.

Public schools aren't how I know the worst parts. For that you have to go back and look at first hand accounts. Even look at some of the lawsuits and laws passed where it was said an owner should be assumed innocent if his slave died during punishment.
