weightism and politics

Is the New Jersey governor's race using weightist undertones as a new campaign strategy?

Opinions differ on whether or not incumbent Jon Corzine is taking jabs at opponent Christopher Christie's weight. The ad says that Christie "threw his weight around" to get out of tickets, and shows Christie "stepping out of an S.U.V. in extreme slow motion, his extra girth moving, just as slowly, in several different directions at once." full article.

Bottom line: weight is a socially acceptable form of discrimination (along with, I'd say, regional accent). Are commentators projecting weightism onto the ad, or is "he's fat" really the implied message? You decide.
