If the Liberals orchestrated the leak, it would explain why the biggest item in their platform – a major tuition break for post-secondary students – was not mentioned in the conference call. This way, other promises – such as a pledge to expand train service for suburban commuters – got more attention than would otherwise have been the case. And when the tuition freeze was revealed on Monday, it not only got a very clean news hit; it also caught off guard the Liberals’ opponents, who thought they knew all the platform’s key planks.
In general, there wound up being more coverage of the platform than would normally have happened – exactly what the Liberals say they were aiming for. And it appears likely the Tories played a part in it.
I speculated along these lines a few days back. Too clever by half? I don't know; they did get an extra day of (mostly) positive coverage. True or not, I'd stick to the story.
