Presidential propaganda meets pizzeria. A Warren, Mich. pizzeria is doing its part to support Sen. Barack Obama’s presidential campaign by offering slices in exchange for McCain-Palin signs. Salvatore’s, of metro Detroit, has reportedly given away hundreds of personal-sized pizzas in just over a week since it began promoting the trade-off. Some neighbors have complained that teens are stealing McCain-Palin yard signs as a result of the promotion. But Salvatore’s ownership denies any responsibility, saying it only wants Sen. John McCain’s supporters to give up their own materials. McCain recently pulled major campaign resources out of Michigan in light of Obama’s lead in polls. Now, Salvatore’s says residents should “pull out on” McCain.
