"Democratic presidential candidate John Edwards told a labor group he would ask Americans to make a big sacrifice: their sport utility vehicles.

The former North Carolina senator told a forum by the International Association of Machinists and Aerospace Workers in Lake Buena Vista, Florida, yesterday he thinks Americans are willing to sacrifice.

Edwards says Americans should be asked to drive more fuel efficient vehicles. He says he would ask them to give up SUVs."
