Thank you MikeM79!  Your comment is interesting, rational and articulate - and civil!  

You don't include Mr. Scheer on your list.   Does he not meet the second of your criteria?  I'm not in a position to vote for the CPC leader but I am in a position to vote in the next Federal election and so I am interested to see who the next leader will be.  The tent needs to be larger (IMO).
