Thomas Mulcair's butt is not waiting to be kicked by Iggy's chosen woman. I hope for the LPCer's sake they pick a ripe one. Mulcair is very good and will not be an easy one to knock off. I expect they (LPCers) will find it surprisingly difficult.
Adding to the difficulty will be the idea that the Liberals have again decided against a democratic selection of a candidate, continuing the age old practice of benevolent leadership.
The Member of Parliament for Outremont, as awful as that sounds today to the LPCer, is a New Democrat and likely will be no matter who Iggy hand picks for the riding, especially if Iggy hand picks someone. Mulcair is a new breed of New Democrat and not so easily dismissed.
update: I missed Scott's advice to Iggy here.
