Worth a look

Scott Piatkowski is right on target:

Even though many advocates of strategic voting say that they favour a continued Liberal minority with the NDP holding the balance of power, that's not what the Liberals themselves want. If they did, they wouldn't have recruited high profile candidates to run against NDP incumbents. Likewise, they'd be telling people in ridings featuring Conservative-NDP races to support the NDP. You won't hear that from a single Liberal, because they are clearly aiming to crush the NDP. That way, they can return to their habit of campaigning from the left and governing from the right, without anyone to call them on it.

Moreover, even if it happened that we end up with another Liberal minority, I don't support the view that only the total of Liberal and NDP seats matters. I would submit that it is always better to have an NDP MP rather than a Liberal MP to represent your riding. In the last Parliament, there were votes on several key issues in which the Liberals lined up with the Conservatives, including the defeat of federal anti-scab legislation. The only sure way to get an MP who supports NDP policies is to vote NDP.

Not much to add here, other than "amen to that". Give it a read.
