It's more then a little ironic, that an ex-Conservative PM is tasked with smoothing the waters for the Liberals. Mulroney has like every other Conservative, has been roundly criticized over the years even after he has long left the office of PM. If things don't work out, expect to hear he wasn't up to the task , and didn't live up tot he hype. If things do work out expect to hear how great the Liberals are, and how they are so much better then the Conservatives.
