Thanks to Lisa Simpson, I know that the Chinese use the same word for crisis as they do for opportunity. The Stronach defection is as good an example of this as I can imagine.
Hopefully this will force Harper et al into the course of action they should have been following the past 10 months - being the Opposition. By that I mean these words of John Robson: "..opposing the government while offering an alternative program..".
This is not at all to wave aside the "banana republic power tactic". But there is nothing more that Harper can do to tell Canadians that they ought not to vote Liberal based on ethics. Nothing. In fact, he should state this publicly, then go on to promoting his agenda.
Two choice quotes to finish. First, from Damian Brooks:
The people who support Martin - or more accurately, oppose the Conservatives; nobody supports Martin...
And second, from Paul Wells:
It's usually a bad sign for a relationship when your girlfriend refers to you in public by both names.
Truer words were never spoken.
