If we're not going to go for an election now, when will we?
The fact is that we can't cower every time we see a poll that doesn't go our way. This government has to end now, when it's already clear that this budget is pointless, and the corruption has already permeated deep enough to send out the warning shots of the ridiculous. Canadians, frankly, have to buck up and learn to deal with an election. It's not even for the benefit of the politicians, it's for them - it's their decisions, their choices that affect the outcome. If they really feel that calling an election now is such a horrible thing, then we take that bruising; but I guarantee you that it won't be an issue once we start getting into a campaign, much like how it wasn't for the 2008 election for Harper.
Or we could do it your way, and keep up the charade of being anything close to an opposition. Is it better we stand our ground and maybe get knocked for it, or is it better we cower and waste away because of our refusal to do something useful? Either way it's clear the odds aren't in our favour, so why not at least go out with a bang?
