While the Liberals and the media have been whining that the Conservative ads attacking Stephane Dion as not being a leader are unfair, they have been having an effect in the polls. Dion has been coming across as an even bigger whiner, if that's possible.
The Quebec ads have taken a different approach, tying Chretien and his old scandalous crew as millstones round Dion's neck. I am less certain that they will be as effective as the English ads, as they don't use Dion's own words and voice against him, and seem to be more backward-looking than forward as regards the scandals of yesteryear.
Judge for yourself.
