When the constitution was written it had a number of provisions in it designed to protect slavery from being outlawed on the federal level. One was the infamous ‘3/5ths compromise’ where enslaved black people counted as 3/5ths of a person for the purposes of determining how many house members a state got. Another was the electoral college, which took the extra house members of the 3/5ths compromise and made them into extra voting power for the presidential election. People now try and justify it for all sorts of bizarre reasons but one of the biggest reasons we don’t elect the president by popular vote is slavery as the south would have lost every presidential election.
So yes, it’s weird that the presidency is the only office in the entire country where the person with the most votes doesn’t always win, but that’s because it was designed from the beginning to be undemocratic in order to preserve the right to own other human beings as property.
