CHARLOTTE, N.C. (AP) _ Newt Gingrich’s daughter said Tuesday that the former House speaker will “reassess” his campaign after the vote in Delaware, potentially setting the stage for his exit from the Republican presidential race.

Jackie Gingrich Cushman said her father’s campaign is slimmer but still winning over voters who aren’t yet sold on likely GOP presidential nominee Mitt Romney, who was expected to win contests Tuesday in Delaware and four other states.

Gingrich has hung his comeback hopes on a strong showing in Delaware and has spent considerable time there in recent weeks. He has not won a presidential primary since finishing first in his home state of Georgia on March 6.

Gingrich’s daughter said the campaign would re-evaluate its standing after Tuesday’s vote.

“He talked about waiting for results and looking to see what happens and then potentially reassess,” she told MSNBC on Tuesday about her father, who has been under pressure for some time to drop out of the race.

She hinted, as Gingrich has in recent days, that the race is fluid and that a dramatic shift could come at any time.

“You never know what’s going to happen tomorrow,” she said.

Despite trailing Romney in convention delegates and fundraising, Gingrich has vowed to campaign until the party’s late-summer convention in Florida. He has more than $4.3 million in debt.

Gingrich was keeping a pair of scheduled appearances Tuesday in North Carolina, including the first election night party he has held since February.

But in a televised interview Monday, he nodded to the steep climb facing him.

“I think we need to take a deep look at what we are doing,” Gingrich told NBC News. “We will be in North Carolina tomorrow night and we will look and see what the results are.”

For his part, Romney planned an election night speech in New Hampshire, where he logged his first victory on the path to the nomination. Aides said his remarks would focus on the general election campaign against President Barack Obama.

Gingrich acknowledged Romney as the front-runner but said he should take care not to appear cocky.

“It is very dangerous for front-runners to start behaving like they are inevitable because the voters might decide that’s not so true,” Gingrich said in the interview. “Frankly, I think it is a mistake for Romney to kick-off his general election campaign tomorrow in New Hampshire. He has about half the votes he needs to be nominated.”

Romney has won 698 of the 1,144 delegates needed to become the nominee, according to a tally by The Associated Press. Gingrich has 137 delegates.
