Scheer comes across as a pleasant man who stands by his opinions and beliefs with conviction.  He can convey his message without being shrill.  He can also clearly articulate his Party's position with intelligence, not getting off topic or lost in bafflegab, that continues to be an issue for the PM.  He still has to work on addressing questions to the press with more confidence as he initially displays initial nervousness.

Ibbitson is correct.  Scheer can make difficult decisions in regard to who is leader and who will be the team supporting him.  Bernier is not a good #2 man as was in evidence after the leadership vote, when he tried to tarnish a fair vote outcome.   This is what happened to Clark when his opponent, Claude Wagner, continued to criticize Clark after the convention which undermined the effort of securing a base in Quebec.   This was a problem that plagued Clark throughout his leadership of the Party.  Voters do not support Parties with unity issues.
