Newt Gingrich, Delaware | featured news

Newt Gingrich hinted he may withdraw from the presidential race if he has a poor showing in the Delaware primary Tuesday – a state where he has been actively campaigning for several weeks. "I think we need to take a deep look at what we are doing," Gingrich told NBC News in an exclusive interview on Monday. "We will be in North Carolina tomorrow night and we will look and see what the results are."

After a three-week lull, the Republican presidential primaries resume on Tuesday when five Northeastern states -- Connecticut, Delaware, New York, Pennsylvania and Rhode Island -- have their say.
