NEW YORK (CNNMoney) -- President Michele Bachmann has a promise: $2 gas.
"Under President Bachmann you will see gasoline come down below $2 a gallon again," Bachmann told a crowd Tuesday in South Carolina. "That will happen."
Sure, politicians promise all kinds of things on the campaign trail. But Bachmann, a leading contender for the 2012 Republican nomination, is wading into truly tricky territory.
The price Americans pay at the pump is tied to the crude oil market -- a global system largely beyond the reach of Washington.
It's certainly true that prices -- now about $3.50 a gallon on average -- have risen since President Obama took office.
"The day that the president became president gasoline was $1.79 a gallon," Bachmann said. "Look what it is today."
Of course, that's not the full story.
When Obama took office, the country was mired in a terrible economic contraction.
"That was in the 4th inning of the greatest recession of our lifetime," said Tom Kloza, chief oil analyst at the Oil Price Information Service.
During recessions, demand for gasoline plummets as trucks pull off the road, companies cut back on travel and laid off workers drive fewer miles.
Obama's desperate SPR oil play"You have to be careful what you wish for because the recipe for cheap prices these days is economic disaster," Kloza said.
Since early 2009, the economy has recovered somewhat and demand for crude has risen. It has even spiked in the developing world -- especially in China, India and South America.
Kloza said that increased crude demand is the principal driver behind higher gas prices.
"We're going to have to recognize the rest of the world has this increasing appetite for oil," he said. "If we go below $2 a gallon, it probably means there has been a lot of wealth loss and we are in a deflationary period."
There are some measures that could be taken to lower gas prices, according to Phil Flynn, a senior market analyst at PFG Best.
