Despite only winning two states so far, Gingrich said he remains the conservative option in the race.
Gingrich said he expects to do well in North Carolina primary.
"I'm the only candidate in the race who has helped balance the federal budget for four straight years and I think, for a lot of North Carolina conservatives, that's a very real achievement that they'd like to see us get back to," said Gingrich.
Despite the candidate's optimism, Francis De Luca, who runs the conservative Raleigh think-tank Civitas, told ABC11 that Gingrich is in a political death-spiral.
"He doesn't have money. So, he can't raise money," said De Luca. "He loses public support, can't raise money because he's losing public support. In politics, seen as not being able to win, you've got to recognize that you're not going to win."
After Gingrich's stop in Raleigh, he headed to Delaware and then back to Wilmington, N.C. for a rally and fundraiser.
The North Carolina primary is May 8.
