Check out this great article by Andrew Stewart today in the Owen Sound Sun Times. Andrew served on the Ontario Students' Assembly on Electoral Reform as a rep from Bruce-Grey-Owen Sound.
Here's an excerpt:
"The beauty of this [MMP] system is the way it combines local representation with a mechanism for proportionality: the number of seats held by each party reflects the proportion of the votes they received.
"In the system we have now, a significant percent (often over 50%) of votes don't matter. That is, even though the voter casts a ballot for the party or candidate he or she believes is best for the job, if that candidate fails to win a seat, that vote is wasted.
"In our democracy everyone is equal, so why should we tolerate a system in which votes do not carry equal weight?"
