Part of the problem is that electoral systems are sticky. As you say, they don't change easily or often. If you get it wrong, then you might end up stuck with it. If it ends up benefiting one particular party or a couple of parties at the expense of another, then you might have the public and partisans saying, “Look at what this process has delivered to us. It's delivered this system that is benefiting some parties and not another.”
It's not like first past the post doesn't do that already, but when you're going to change something so fundamental as this, it's not going to be ordinary legislation in its impact. There's a risk of getting it wrong.
If we're going to stick to the timeline, to answer that question, I think we need people going door to door. That's the way to do it. We want to go high tech. I have to say, I admire the committee and how it has been working. The travel schedule must be brutal, but the way to do it is door to door. That's what works. We want to go to the Internet. We want to go to town halls. We want to tweet it. We want to have Facebook. We want to beam it into people's brains.
The only thing that works effectively in the long run is door to door with a grassroots engagement, and it can't just be the activist communities. It needs to be political parties and it needs to be MPs and their staff talking to folks one on one. That's the only way to do it. The ground game matters. This is what we go to.
