Delineating the neighborhoods is a challenge. It's like connecting the dots. The bottom line is to try to fairly distribute the tax base, and you do the best you can with what you have.

You can delegate personal duties, but you can't delegate the responsibility for values. It's our signatures on the documents.

The challenge for him is going to be able to put a human face on that and if I have any advice it's to make sure that whoever does not make it into the cabinet is still a very valuable part of the team.

I've always loved a challenge.

The challenge is high. The stakes are important. I think it's manageable.
