Do you not understand that proportional representation distributes power so that no one party has total control?
Do you not understand that if the NDP has 15% of the seats, they can still be ignored if this PM wants them to be? LPC has a majority by itself right now. If you already think Carney's too conservative, the last thing you want is him having a majority with the actual Conservative party's help.
Its why its such a good campaign promise (from Trudeau) and why the Liberals refuse to deliver it
To be clear, Trudeau never promised PR. HE promised election reform. The committee recommended PR and Trudeau noped out.
