I must say, one of the highlights of the Liberal campaign to date, the smart advertising campaign. The latest English ad is a clever attack, because it isn't overtly negative, it merely offers a distinct contrast. The trouble with most attack ads, they run the risk of leaving a bad taste. The beauty of the Liberal ad, it offers as much vision as venom, which leaves the viewer a neutral presentation. By all accounts, the feedback for this ad has been very positive.
I see today that the contrast theme is more than a one off, here is the new billboard campaign for Quebec:
I think the above is a terrific visual, you don't need to pay much attention for the message to sink in. It's also quite shrewd to use the names of the two leaders, a subtle reminder for Quebecers.
The Liberals have clearly found the right balance, and the contrasts are presented in a high signal manner, quite different from the juvenile Conservative attacks ads. Good stuff.
