Newt Gingrich suggested Monday that the end may be near for his struggling presidential campaign.
In an interview with NBC News, the former House speaker acknowledged that he would have to "reassess" his bid if he fares poorly in Tuesday's Republican primary in Delaware, a state where he has spent considerable time campaigning.
"I think we need to take a deep look at what we are doing," Gingrich said. "We will be in North Carolina tomorrow night and we will look and see what the results are."
He told NBC, "I would hope we would do well here — either carry it or come very, very close."
Gingrich has won only two states so far — South Carolina and his home state of Georgia — and his campaign is $4.3 million in debt, according to FEC filings.
Still, Gingrich has refused to bow out. Even after Rick Santorum suspended his campaign two weeks ago, Gingrich insisted that he was "committed to staying in this race all the way to Tampa so that the conservative movement has a real choice."
In Delaware, he also had some words of caution for presumptive Republican nominee Mitt Romney.
"Gov. Romney is clearly the frontrunner but that doesn't mean he is inevitable," Gingrich told a small crowd at GOP headquarters in Wilmington. "It is very dangerous for frontrunners to start behaving like they are inevitable because the voters might decide that's not so true."
