I’m not sure if Approval would weed out extremists in practice or not, but using the current voter behavior under FPTP and extrapolating to Approval doesn’t really hold water. Even in Fargo and St. Louis we’re already seeing different voting behavior, where only 30% of voters chose to be strategic in who they vote for. Under a FPTP election you pretty much have to make a strategic decision.
