Sarah Palin has a new ad featuring women who, the ad implies, are traditional, sensible moms who know best. The ad makes vague statements like "We don't like the direction this country's going," as the camera lingers over blonde, brunette, grey, and white-haired daughters, mothers, grandmothers, of all shades of white, and even one in a wheelchair with "Don't Tread On Me" on the wheelchair's back. That sure sends a message, but I darn well hope that was completely unintentional. Right?
