I hope neither O'Toole nor Raitt drop out.  I DO hope Trost, Saxton, Blaney, Alexander, Leitch and Obhrai drop out.  All extremely unimpressive individuals with absolutely nothing to offer this leadership race (Obhrai seems like a decent dude with a good sense of humour, but is essentially unelectable).  

O'Leary's recent comments regarding the military disqualify him as leadership material, in my opinion.  

Scheer seems to have the support of the party insiders and looks pretty good on paper but is a fairly uncharismatic fellow.  Raitt's French is not good enough.  Bernier has some interesting and appealing policy ideas but will carry the heavy  baggage from his early days in cabinet into a general election.  I still like Michael Chong the most of any of the candidates and will vote for him.  Experienced, young, reasonable French (room for improvement), well-thought out and crisp fiscal policy, can appeal to a broad swathe of the electorate.
