Yesterday, Carney more directly targeted Gingrich, who has in recent weeks said he would drive gas prices down to $2.50 per gallon by expanding drilling further into offshore and federally-owned areas. The former Speaker has made the promise a cornerstone of his campaign, featuring the pledge prominently on the stump and in campaign commercials.

"What [President Obama] is not willing to do is to look the American people in the eye and claim that there is a strategy by which he can guarantee the price of gas will be $2.50 at the pump," Carney said yesterday. "Any politician who does that is lying."

Gingrich spokesman Joe DeSantis said Carney's pivot was evidence the House Speaker was "in the president's head."

“The idea of this administration, which has brought us a failed stimulus, boondoggles like Solyndra, $5 gasoline and record budget deficits, lecturing anyone on economics, would be funny if their utter incompetence weren’t so painful for the American people," DeSantis said in a statement.

Monday night, Gingrich said at a candidate forum that his plan was threatening to the White House.

“I have suggested that if we developed our energy capacity to the degree we could, that that would bring down the price of gasoline on the theory that supply and demand works, and this is not something that Obama is very used to. This is not a bureaucratic trickle-down, shovel-ready, Solyndra-investment, let’s-go-bankrupt-together policy," Gingrich said.
