Columnist Linda McQuaig wrote a great piece in today's Toronto Star on the referendum entitled, "Democracy well served by reform".
Here's an excerpt:
In Canada, where the electorate is fairly progressive, the result would generally be more progressive representation in the legislatures. (As Tom Flanagan, a strategist for Stephen Harper in the 2006 federal election, noted in his recent book, Harper's Team: "Neither the philosophy of conservatism nor the party brand comes close to commanding majority support.")
...Indeed, it's interesting to note that, under an MMP system, Mike Harris would never have won a majority government. Nor would the NDP's Bob Rae. Neither of these leaders had the support of the majority of Ontario voters.
Instead we would have ended up with governments that more accurately reflected the generally centrist-progressive nature of Ontarians. Anyone who has a problem with that has a problem with democracy.
