Need A Ride to the Polls? Ask Warren Buffett

"I will have spent over $100 million on my own campaign. Meaning ... I don't have to take the money from all the fat cats that are going to tell you what to do. I think it's a big asset. It doesn't get talked about much," Trump said on Monday on Fox News.

This is a promise Trump has been making for a year and a half — that he'd spend more or close to $100 million dollars on his presidential bid — and it's been hard to fact check that until now.

He hasn't: Trump has spent just more than $66 million on his campaign, according to required FEC filings. After the final October filing date, campaigns are required to report large donations within 48 hours, so as of Election Day, it's clear that Trump is still $34 million short of his promised goal.

The candidate is also wrong to say his decision to partially self-fund is not discussed often: It's been reported on at length in the media and supporters often cite it as a popular feature of the candidate.

There were the secret Donald Trump supporters, secret Hillary Clinton supporters, people who claim to vote but have never done so, and boyfriends, girlfriends, husbands and wives contemplating break-ups over their significant others' politics — to name a few.

What started as an experiment ultimately shed light on a previously hidden aspect of the American body politic to tell a — sure — non-scientific, but human, complex and nuanced story about one of the most contentious elections in recent memory.

Here are some of the most pointed confessions (and favorite confessional moments) of the 2016 election — your secret's safe with us.

Warren Buffett is offering a helping hand — and a set of wheels — on Election Day.

The billionaire investor and staunch Hillary Clinton supporter is offering rides to voters who need a lift via trolley in Omaha, Nebraska as part of his "Drive 2 Vote" campaign. Buffett has said the goal of the initiative is to have the highest percentage of turnout in any district of the country — regardless of party.

Before giving out rides, Buffett was spotted waiting in line to vote at a church in his hometown.

The 86-year-old Buffett has joked that his eyes are good enough to drive and that he'll even allow selfies. "You bet they can take selfies," he has said. "We're not going to a funeral."

NBC correspondent Katy Tur spotted a woman wearing an actual Trump sign at his final rally in Grand Rapids, Michigan.

The popular Make America Great Again hats were apparently too basic for this Trump supporter. She opted to show her enthusiasm for the candidate by attaching a crumpled Trump-Pence 2016 sign to the back of her outfit. How she managed to attach it is a mystery.

A missing poll book caused major problems for some voters at a Brooklyn voting site.

David Riemenschneider, 35, said he showed up to his polling place at 671 Prospect Place shortly after 6 a.m. Tuesday. He said the on-site inspector told him and others "that the book that had all of the last names N through Z in it…was not at the polling place. So what I was told was that they couldn't give us ballots because we couldn't sign for them."

"'The place that has the books doesn't open until 9,' the inspector said, according to Riemenschneider. "'We'll hopefully get it before 9:30 or 10, so come back later.'"

He said no provisional ballots were offered.

"I will hopefully be able to go back later," Riemenschneider, who teaches in Manhattan, said. "The big concern I have is what about the people for whom, that's the only time? They were told, 'Sorry, you just can't vote now.' It had nothing to do with being registered or not. I'm confident there are people who went to vote who will not vote now because of this situation."

"We're not talking about a technical error," he added. "To just not have the materials there, and not to have a voting inspector who knows enough to be able to say, 'Oh, actually, there is an alternative…That's what I find really frustrating."

He said he reported what happened to the Board of Elections.

The Board of Elections has not responded to NBC News' calls.

Pennsylvania has seen widespread reports of voters wrongly being asked for identification by poll workers, according to Election Protection, a coalition of organizations monitoring voting.

Two voters told NBC News they had been asked for photo ID.

"I recently moved into my voting area, so I brought everything with me, and I figured I would hand them my voter registration card," said Nicole Sorgini, 27, of Philadelphia, who voted at the Cook Wissackon School.

"When I handed it to them they said, 'No, I need your driver's license,' and someone else in line said, 'Oh, I only have my voter ID card.'"

Poll workers then told them they require driver's licenses for new voters, Sorghini said.

"I had my driver's license so I just used that, but I told them technically under the law, you can use the voter ID card."

Sorgini said she called Election Protection to report it.

"I'm thinking she was maybe just misinformed," Sorgini said of the worker. "But it was worrisome because there were a lot of new voters there, and you don't know if everyone had photo ID."

Ryan Kellermeyer, 39, also of Philadelphia, said when he showed up to vote at Cayuga Elementary, the poll worker asked him for ID. He told her it was not required and said she insisted. Ultimately, he said, she allowed him to vote without showing ID.

"I think she wasn't trained very well," said Kellermeyer, who has voted at the location before and believes the worker was new. "I was told by others she had been asking everyone for ID."

Kellermeyer said he reported it to a pollwatcher and to Clinton campaigners outside. Although he does not think it was nefarious, he is concerned that some people might be dissuaded from voting.

Under Pennsylvania law, ID is required for new voters or voters voting at a new site for the first time, but photo ID is not required. A photo ID law passed in 2012 was blocked ahead of the 2012 election. It was struck down by a court the following year.

A spokeswoman for the Pennsylvania secretary of state's office did not immediately respond to a request for comment.

With Democrat Hillary Clinton poised to potentially become the first female president in the history of the United States, there has been a surge of interest in feminist icon and suffragette Susan B. Anthony.

She was a trending topic early on Election Day, and reports have surfaced that there has been a huge spike in visitors to her tombstone in Rochester, New York.

Enthusiastic citizens have been attaching "I Voted" stickers to her gravestone in tribute to her historic effort to win the right to vote for women, a movement which was ultimately successful in 1920. Anthony died in 1906 having never had the chance to realize her dream of American women participating equally in democracy.

Although her gravesite is usually closed to the public after 5:30 p.m., Rochester Mayor Lovely Warren told the Associated Press on Monday that posting the stickers was a "rite of passage for many citizens" and she has extended the time for visitors until 9 p.m. on Election Night.

Meanwhile, Clinton, who has openly embraced the groundbreaking nature of her White House run, is believed to have been paying homage to Anthony and other suffragettes with her choice of an all-white pantsuit at the Democratic National Convention in July and again at the third and final general election debate.

As of November 8, 46,314,207 early votes have been cast in the 2016 presidential election, setting a record for early voting. The NBC News Data Analytics Lab uses voter data from TargetSmart to analyze early vote totals.

There are likely millions of early votes still to be tabulated, so this number could grow over the next few days.

By comparison, the Associated Press tabulated that 46.2 million early votes were cast in the 2012 election.

Sen. Tim Kaine cast his vote for the 2016 election in his home state of Virginia this morning.

The VP candidate returned home to Richmond the day before for his final rally of the campaign. He was visibly emotional, wiping tears from his eyes as he greeted the crowd at the airport hangar in Richmond. "Is this happening?" he asked.

Kaine arrived to his polling place — the Hermitage Methodist Home in Richmond — with his wife and parents. He was 15 minutes early to vote and ended up being second in line. "I wanted to be first at my polling place, but 99-year-old Minerva Turpin beat me to it. Looks like I need to get used to being number two!" he tweeted.
