Can Michele Bachmann 'promise' $2 a gallon gas?

Rep. Bachmann told a crowd on the campaign trail she could promise $2/gallon gasoline as president– a claim that, according to CNN's Joe Johns, was “completely fact-free.”

Johns went through Bachmann’s comments and followed up with experts explaining how gas prices work – they are set internationally, with the president having very little to do with it.

As for how prices can drop to that specific price Rep. Bachmann promised, Johns noted somewhat wryly that “about the only way for the price of gas to drop to $2 is for the entire global economy to tank” – something that could happen with the influence of an American president, but doesn’t really make for an appealing campaign talking point.

Johns turned then to CNN financial reporter Ali Velshi, who emphatically attacked the promise as an “entirely irrational, baseless claim, not doable.” If it did happen, he added, “the most likely way to do that is a global depression.”
