The way we did it the last time...and we're in agreement with the first round and the second round. I think the trick is the third round. Whether you go back to the first round or the second round, it's unlikely, to be frank, that you're going to get to the Liberal position even if you did go back to the first round, to 7, 7, and 7. That's the position we in the NDP were in the last time, and we rarely got to that position, but it did happen on occasion.
