I'm wondering how best to get pledges from the Liberals who might survive to not pull a David Emerson, the former Martin Liberal from Vancouver, who between E-Day and the cabinet swearing in had a conversion from the Liberal banner he was elected under to the Harper Conservatives, who were now the one's in charge.
I think it would need to focus on the wide policy differences between the Tories and the Liberals (at least on paper both Jack and Iggy had, until the surge hit, pointed to the commonality between Liberal and NDP platforms) so that voters know that they don't have to worry about voting for the "red" door and getting their MP walking through the "blue" door. (Would make a good political cartoon should it happen, I suppose.)
Thoughts?
