In our current system, you can't really promise anything, because you don't know if you will be part of the government at any point in time. You can't really promise results. Therefore, you have to do your part in trying to deliver as much as you can for your riding.
It's something that I think we have to really examine ourselves. That will take a bit of time. I also studied political science in university, so I studied various models in school. With the models that I've looked at, I have issues and concerns regarding proportional representation.
Look at our country. We had the Bloc not too long ago. I didn't really enjoy watching that part and the way our country was fractured into cultural, linguistic, and regional factions. Yes, the current system has its flaws, but it's better than proportional representation. In trying to govern, a minority government is at times stable, but it can create a lot of instability, and I don't think we need that.
