It's not three fifths of a person, bro. I can't let that one go because it iritates the hell out of me when someone says that. For purposes of the Representation and taxation they were including only three fifths of the slave population in calculating the total population of the state. It was done to minimize the political power of the Southern states because the number of Representatives in the House is determined by the population of the state. Read the damn language for yourself.
Representatives and direct Taxes shall be apportioned among the several States which may be included within this Union, according to their respective Numbers, which shall be determined by adding to the whole Number of free Persons, including those bound to Service for a Term of Years, and excluding Indians not taxed, three fifths of all other Persons.
Better get to the democrat message boards.
BRO!
