2020 Democratic candidates are claiming their own Iowa caucus results to fill the vacuum caused by a technical delay. Here's what they're saying.

Jeff Weaver, a senior adviser for the Sanders campaign, released the campaign's "internal reporting numbers" in an email early Tuesday morning.

The campaign said these figure represent the results from nearly 40% of Iowa precincts, and collected by Sanders volunteers across the state.

The preliminary figures showed Sanders gaining 29.66% of the vote, with Buttigieg coming second with 24.59%.

Sanders also said Monday: "I have a strong feeling that at some point the results will be announced and when those results are announced, I have a good feeling we're going to be doing very, very well here in Iowa."

"It's gonna be close. We're gonna walk out of here with our share of delegates. We don't know exactly what is it yet, but we feel good about where we are," he told supporters in Des Moines.

"I feel good," she told reporters after she landed in New Hampshire early Tuesday morning.

Earlier, on Monday night, she had told supporters in Des Moines that the results were "too close to call."

Yang didn't say anything about the Iowa caucus results, but remained optimistic about the next caucuses in New Hampshire.

In a Monday night speech in Iowa he thanked his supporters and family, saying he "shocked the world time and time again."

He was also optimistic, saying: "I'm going right from here to New Hampshire, where I will be one of the seven candidates on the debate stage on Friday night."

Klobuchar told supporters in Des Moines: "We know one thing: we are punching above our weight."

"Somehow, some way, I'm going to get on a plane tonight to New Hampshire," she added.
