Here's the latest salvo in the gas-tax war -- a new TV ad by Obama running in Indiana and North Carolina:
Announcer: "More 'low road' attacks from Hillary Clinton…Now she's pushing a 'bogus' gas tax gimmick… Experts say it'll just 'boost oil industry profits'... They'll 'simply raise prices and pocket … the difference.' Clinton aides admit it won't do much for you – but would help her politically. So here's the choice…Clinton gimmicks that help big oil… Or Barack Obama… a real energy plan and a $1,000 middle class tax cut to help families truly pay the bills."
