So she'll do OK- and I agree that the lack of decent French amongst RoC MPs is a disgrace.
If Layton resigns, it will be Mulcair by a country mile. There is quite literally no one else, since Nash or Davies are completely unsellable to the public.
Peggy Nash would be fine, although I have not been impressed with her interviews, as she doesn't answer questions directly, or even close. But that's just politics.
Davies wouldn't be very sellable. I haven't liked her since I saw her ride first class on the plane back from Vancouver. What kind of socialist rides first class!?

Each could mount a credible campaign (though the latter 3 would need to be able to speak french) and if they all ran and an anti-mulcair thingy developed (not as unrealistic as you might think) then one of them could certainly win.
1. Unknown (but has potential)
2. Too old (but that's his only draw back)
3. Too hated (but then again, so was Jack)
4. Unknown outside of New Brunswick (and where has she been lately?)
