IDK, Raitt, Chong, and maybe Scheer might have a broader appeal to Canadian voters, but I expect the party is going to go with a more popular but less mature candidate.  (Of course I hope they pick O'Leary for the entertainment value!)  I'm a "progressive" voter, but I'd rather they picked someone who can uphold conservative values and speak to important public issues from the right, because we need better politicians on both sides of the aisle.
