Does the popularity vote even matter? I remember someone telling me that in the last US election, Al gore had 500 000 votes more than george bush, yet Bush still won the election. I dont know how the US system works
It's because of the electoral college system. It makes sense to some degree, but it's a bit weird, and allows for this disparity. It's a bit complicated so I'll use a simple analogy:
It's like if heaps of people in my electorate, Batman, votes for Labor (70% of the vote), then that's only one seat for Labor, despite all these extra votes going in for them which don't really "count" in a sense. Meanwhile, Liberal might be winning most their seats with barely above 50%, so Labor might still get more votes overall, but because of the way the electorates are split up, Labor might get less seats.
