(CNN) - Newt Gingrich may reconsider his White House bid if Tuesday night ends with a disappointing finish in Delaware's primary, the former House Speaker said Monday.
Invoking language typically used this cycle by candidates shortly before dropping out of the race, Gingrich recognized he would need to "reassess" his campaign depending on Tuesday's results.

"I think we would need to take a deep look at what we are doing," Gingrich said in an interview with NBC News. "We will be in North Carolina tomorrow night and we will look and see what the results are."
A winner-take-all state, Delaware has 17 delegates up for grabs. The candidate has made frequent campaign stops in the state in recent weeks, hoping to snatch at least one victory among the five states holding contests Tuesday.
"This has been a good opportunity for us, we have been here seeing a lot of people," Gingrich said. "We have got really positive responses, and I would hope we would do well here – either carry it or come very, very close."
Gingrich, having won only primaries in South Carolina and Georgia, trails far behind Mitt Romney in the race, with 141 delegates to Romney's 695 delegates, according to a CNN estimate.
He has repeatedly said he would stay in the running until Romney secured the 1,144 delegates needed for the nomination, adding that he would then throw his support behind the likely GOP nominee.
Even if Romney were to win all the delegates at stake Tuesday night, however, the former Massachusetts governor would still not hit the 1,144 mark.
Campaign finance reports last week showed Gingrich's campaign was $4.3 million in debt. And the candidate came under recent scrutiny for holding onto his Secret Service protection-at a taxpayer cost of tens of thousands of dollars per day-despite his declining position in the race for the White House.
Gingrich has seen continued support, however, from his biggest benefactor, casino mogul Sheldon Adelson, who's family donated $5 million last month to a pro-Gingrich super PAC.
As results pour in Tuesday, Romney is expected to make a big general election speech in New Hampshire, the battleground state where he first launched his campaign last year. Gingrich, meanwhile, had some choice words for the all-but-certain nominee Monday night.
"Gov. Romney is clearly the frontrunner but that doesn't mean he is inevitable," Gingrich said at the GOP headquarters in Delaware. "It is very dangerous for frontrunners to start behaving like they are inevitable because the voters might decide that's not so true."
