Gingrich was in Raleigh last week before he continued with his campaign trail.
Despite only winning two states so far, Gingrich said he remains the conservative option in the race.
"Every vote we can get in North Carolina is a vote for a more conservative platform," Gingrich said Monday. "We're campaigning here, we're campaigning in Delaware. I think Romney has some huge advantages. Until Romney gets to 1,144, there's no reason to concede anything. But you have to realistically recognize this is a Wall Street based money machine."
The North Carolina primary is May 8.
