Scheer is off to a good start? How can you write that? Most Canadians haven't even heard of scheer. He got no 'bump' after the (dumb) selection process. And he's done nothing positive since.
And, since you started the subject, very few voters liked harper by the end of his time. His nastiness was showing thru, and his 'common sense' turned into boutique  tax breaks and driving away large sections of voters. If you want to think of that as 'common sense' I suggest you have an odd view of that trait.
