Chattanooga, Tennessee (CNN) – Newt Gingrich attacked U.S. Middle East policy as he barnstormed Tennessee in a final attempt to win over voters on the eve of Super Tuesday.
Crowds at his four Monday events appeared to rally behind his idea of an "American energy policy," and becoming more "independent of the Middle East."

"[W]e need rethink what we're doing across the whole region and arguing about Afghanistan today and Syria tomorrow and Iran next day - this is nonsense," Gingrich said in Knoxville.
Gingrich questioned America's complicated diplomatic relationship with Pakistan, after he claimed the country's leaders "apparently were hiding [Osama] bin Laden for at least seven years."
"I've got to tell you, when you give somebody $20 billion, you call them your ally, you find out that they have been hiding your number one terrorist, I get pretty darn angry," he said. "When you find out they in fact are going after the people who had been helping us, I get a lot more angry."
Gingrich criticized President Barack Obama for apologizing to Afghan President Hamid Karzai after religious materials were recently burned on a military base.
"At some point in the near future the children's hour has to end and we have to get back to adult supervision in national security," Gingrich said.
The campaign took to the street Monday, distributing gas-pump signs in the cities of Kingsport, Alcoa, Knoxville, and Chattanooga. His pitch calls for $2.50 per gallon gasoline.
Gingrich denied recent claims by Republican opponent Mitt Romney that he was pandering to voters when he talked about lowering the cost of gas.
"[Romney] said, you know, this is pandering. No, this is called leadership," Gingrich said Monday. "The way you change patterns is that you have leaders that change goals so you can rally the American people and together you go out and you achieve the goals."
"So let’s have a new American strategy for the Middle East called 'make enough oil here at home' and 'enough natural gas here at home' to tell them they have a problem because we don’t care."
In addition to the four campaign stops in Tennessee, the former House speaker was busy with more than 20 local and national media interviews.
The former Georgia congressman is expected to win his home state, where he spent four days campaigning last week and where he will be election night.
But recently, Gingrich invested more time and money into neighboring Tennessee after polls indicated the Republican presidential candidate might be gaining ground there.
Gingrich said he is hoping to pick up delegates in most of the 11 contests held Tuesday, but also is looking ahead to Kansas on March 10 and Alabama and Mississippi on March 13 to deliver the delegates he needs to remain a viable candidate.
