A two party system was one of George Washington’s fear. It breeds division while both sides occupy themselves making us emotional about how much the other side does wrong. Then they get more donations and more power. They don’t care if they aren’t effective because they know we won’t ever go to the other side.

My takeaway - support rank choices voting and elimination of closed primaries (which encourage extremism in candidates).
