Snagged! In a recent speech, John Edwards told Americans to sacrifice their inefficient cars, and specifically, to give up their SUVs. But the presidential hopeful is driven around in a Cadillac SRX Crossover, which guzzles gas at 15 miles per gallon. His spokesman says that he drives a hybrid SUV in North Carolina, but reports say the Edwards family has a regular SUV and a small truck as well.
