The new Dion ad is perfect in tone and addresses the key concern. I've already argued that Dion needed a presentation that highlights his leadership ability, and this ad picks up on one of themes.
I think it is simply brillant, the portion of the ad that has Dion sitting at the climate conference table, with the word PRESIDENT clearly visible. Dion raises his arms in victory, and you get the sense of accomplishment. Fantastic imagery, and a clear signal that the Liberal braintrust understands the challenge.
This type of ad also allows Dion to claim the high ground. The Tories roll in the muck, the Liberals choose a positive message. That theme is a key one, mean-spirited partisanship vs possibilities, something which will resonate well with Canadians.
If Dion can show Canadians that he is a leader, and there are other examples at hand, then the Liberals have a real chance come the next election. I view this ad as confirmation that strategists know the plot, and it represents a great first step in introducing Canadians to Dion. Well done.
