I have heard from enough sources that OLPR was about winning the voting-system wars. “Enough” means enough to merit comment.
OLPR was arrived at in several ways:
1) Does what STV does with less administrative headache.
2) Does what STV does while addressing pathologies in its past operation.
3) Has to be the go-to federally because MMP seems unconstitutional.
4) Has to be the go-to generally because “all” agree that closed-list PR is a “nonstarter.”
Have a good Independence Day weekend.
