You are thinking of an individual: Jacob Chansley, who called himself the Qanon Shaman. He recently dropped out of the race for US Representative in Arizona’s 8th District (northern Phoenix metro area). He was actually running as a Libertarian – nothing to do with MAGA. Of course, he was just trying to get noticed.
The 3/5 issue was about representation, not particular votes. There is a reason the South did not politically dominate the north, and that was at the heart of it. The effect is clear if we imagine it extending to the entire population of the south. The voting power in congress was diluted.
In actual numbers, the 1860 US census recorded 12,240,296 citizens in the slave-owning states. 32.2% of the citizens of those states – 3,950,343 people – had only 60% representation in Congress.
The US population in 1860 was 31,443,320: the South comprised 39% of that. Even without the 3/5 rule it was outvoted. With the 3/5 rule the voting power had dropped to a clear minority: 23%.
Effectively, the South as a bloc carried 23% of the voting power in Congress. It never matters which state a US President comes from; Congress makes the laws.
