That's a feature, not a bug. The system grants more weight to the voices of those who are thoughtful and contemplative in their selection than it does to lemmings. PewDiePie may have eleventy billion constituents, but he still only gets one vote.
I'm guessing the numbers won't be known until after the voting is done, meaning a lot of effort will be spent finding out where the line is at.
I kinda want to simulate it for a few elections to see what happens, but there isn't any sufficient simulation.
