Wal-Mart defends itself against irrational critics with a slick political-style ad. Says AdAge magazine:

The new national push represents a dramatic shift away from recent
campaigns focused on the retailer’s merchandising efforts to woo more
affluent shoppers. These ads instead aim to appeal to working families
by promoting a study financed by Wal-Mart that finds the retailer saves
the average family $2,300 a year.
