The Hill: Rep. Michele Bachmann (R-Minn.) is doubling down on her vow to drive gasoline prices to less than $2 per gallon if she's elected president, a pledge that 2012 GOP rival Jon Huntsman said isn't rooted in the "real world." Bachmann drew attention last week when she pledged at a Tuesday campaign stop that "Under President Bachmann you will see gasoline come down below $2 per gallon again."
