He is a smart, successful guy.  You need a smart, successful guy as Finance Minister.

But you also need a guy with sound judgement.  He could have easily said at the start "well, the ethics commissioner says I could do x and y but I don't have to.  But you know, it looks right and smells right to do it so I will anyway".

I fear we have a smart, successful guy with no real sense of sound judgement.  Not good as a Finance Minister.
