... and it's both racist and corrupt. I agree we need reform if we're to survive. Between BLM this spring, DC now, the fringe militant elements, we're seeing more and more violence.
I will mention that the split-down-the-middle thing isn't a property of electoral college. That's how you win in a democracy. If voters are distributed between 1 and 10 on some issue:
1-2-3-4-5-6-7-8-9-10
I win by picking 5.5. Whatever you pick, you get a minority of voters. That's complicated by primaries. In the same system, if I want to be a ballot candidate, though, I can't do that. I want to pick 2.75 or 7.25 so the majority of my party votes for me.
Of course, things like charisma fit in a bit too, but for the most part, if one party runs a 2.74 candidate and the other a 7.24, the 7.24 has an advantage, and vice-versa for 2.76 and 7.76.
All that things like electoral college do is shift weights. Tight elections just means politicians have learned to play the game well.
A system where someone with 40% or 60% of the vote wins isn't fundamentally broken -- the underlying check-and-balance works. What is fundamentally broken are when incentive structures misalign.
