Paul Dewar (could be added to the list)
Some people think Libby Davies would run, but I don't think she'd manage to get more than a dozen votes - and I don't mean delegates.
I don't think Libby Davies would run in any case. She speaks no French which would be an immediate disqualification. I don't really care about who is or is not a "household name". The fact of the matter is that almost no one in an opposition caucus is ever a "household name". How many people do you think had ever heard of Layton when he first became leader. The people I would see as possibilities (moving from east to west) would be as follows:
Jack Harris (apparently incredibly intelligent - French is so-so)
Megan Leslie (maybe too early for her)
Thomas Mulcair (nothing more need be said, bilingual, former Quebec cabinet minister, but apparently rubs a lot of women in caucus the wrong way...)
I wish i could name anyone else in Quebec, but they are all too inexperienced at this stage.
Peggy Nash (she speaks very good French and presents very well etc...)
Charlie Angus (seems hip, speaks passable French)
Peter Julian
...and then there is always the possibility that Doer comes home to take the reins! who knows.
