Outremont isn't a slam dunk return to the Liberal column by any means, which means any counter-productive "development" denotes PURE FOLLY. I couldn't give a rats ass what Coderre wants, nor is Cauchon's personal ambitions of any concern. The Liberal members of Outremont should decide who represents them, so glaringly obvious it hurts.
It's actually a positive, that two impressive figures want to carry the Liberal banner. Let those two individuals appeal to the grassroots, and may the best person "win". The LAST thing you want is a process that leaves bitter feelings, that effectively turns off people that will be crucial in an election. Why would you want to shutout Cauchon, and alienate what I assume is a large following of Outremont Liberals?? That type of process essentially volunteers unnecessary weakness and benefits Mulclair. I see this debate as a question of arrogance- only a fool doesn't put their best foot forward, maximize every intangible to present your strongest hand. Hard feelings, excluding Cauchon and his pedigree, is frankly NUTS in the grand scheme.
If Liberals are "determined to win back Outremont", then put aside silly turf wars and have a spirited contest. Get it right in Outremont.
