As Super Tuesday, the single biggest day of voting gets underway, the candidates are competing across 15 contests for a treasure chest of delegates, which will be awarded across geographically and racially diverse parts of the country.

The stakes could not be higher as Democrats face a significant turning point in the 2020 presidential race and are tested on a national scale.

Across 14 states -- Alabama, Arkansas, California, Colorado, Maine, Massachusetts, Minnesota, North Carolina, Oklahoma, Utah, Tennessee, Texas, Vermont and Virginia -- and one territory, American Samoa, 1,344 delegates are up for grabs.

Here's how the day is unfolding. Please refresh for updates.

Following an unusual joint warning on Monday to countries or other foreign actors that might attempt to interfere in the nation’s Super Tuesday primaries, a senior Cybersecurity and Infrastructure Security Agency official says there were no reports of malicious activity.

The official says that they were looking to look into some brief technical issues that touched on three states: Minnesota, Texas and California, but nothing indicated that there was any malicious actor involved. This official said the systems are up and running throughout the states.

In a statement responding to Super Tuesday results, the Trump campaign cheered on the chance that Democrats could be headed for a contested convention while slamming a resurgent Biden as a "terrible" candidate and pushing the narrative that "establishment Democrats" are working to stop Bernie Sanders.

"The media is hyperventilating about Joe Biden, but everyone should remember that he is just as terrible a candidate right now as he was a few days ago," Brad Parscale, Trump's campaign manager, said in a statement.

Parscale also said "establishment Democrats have ganged up" to deny Sanders the Democratic nomination, saying it is causing "more mayhem."

"Even if Bernie is not on November’s ballot, his big government socialist ideas will be because they have become mainstream in today’s Democrat Party," he continued.

11:13 p.m. Warren asks supporters for more donations ahead of next six primaries

But here’s the bottom line: There are six more primaries just one week away, and we need your help to keep up the momentum,” the letter says. Another breadcrumb for those who are on dropout watch.

11:07 p.m. Sanders' campaign seeks to keep California polls open past 8 p.m. PST

The Sanders campaign has filed a complaint demanding that polls stay open past 8 p.m. (PST).

"This Complaint and Demand for Injunctive Relief seek an emergency temporary restraining order and injunctive relief to prevent polling locations in Los Angeles County (the “County”) from closing at 8 p.m. today, to ensure that Los Angeles County voters can exercise their constitutional right to vote," the filing read.

The complaint went on to say that multiple polling locations in the county experienced extreme wait times – some as long as four hours – to cast a ballot. The filing also highlighted a new proprietary voting system called “Voting Solutions for All People” that was being used for the first time on a wide scale.

“The new technology has resulted in problems because of check-in stations not working and machine failures, with insufficient or overwhelmed tech support and an inability to implement back-ups,” the filing said.

According to the complaint, the polls should remain open until 10 p.m. and to offer provisional ballots to any voters who arrive at the polling places after 8 p.m.

They say he's not getting out ‘yet’ – yet being the operative word here,” Vega reports. “The campaign is saying he will keep battleground offices open, that he is pledging to help whoever the nominee is, if it’s not him, that going forward he will invest his money in a Democratic candidate.”

10:48 p.m. Ad spending reminder: Biden spent significantly less on ads compared to his rivals in some of the states he's won so far

As Biden continues to net victories in Super Tuesday states, here's a reminder of how significantly less Biden spent compared to his rivals in some of the states he's won so far.

In North Carolina, where Biden is enjoying a big lead, the former vice president has only spent about $321,000 on ads, less than a fifth of the $1.7 million Sen. Bernie Sanders spent there.

With an 11th-hour endorsement from Klobuchar, Biden also just won Minnesota, where he only spent just a little more than $6,000, compared to more than $254,000 Sanders spent in the state.

Biden also won Arkansas by spending just about a fourth of what Sanders spent in the state and Tennessee by spending less than a third of what Sanders spent there.

Notably, Alabama and Virginia, which also sided with Biden, are two states where Biden spent more than Sanders.

And Bloomberg of course spent seven-and-eight figures in all of those states and has so far only won American Samoa.

The latter part of his tweet was in reference to a video posted on her Instagram story shortly after announcing her presidential exploratory committee.

7:27 p.m. Trump mocks Bloomberg on Twitter, references coronavirus threat

As Super Tuesday results continue to come in, Trump went after Bloomberg on Twitter with a video of the former mayor licking his fingers while eating pizza at a campaign stop.

The president, a self-described germaphobe, mockingly warned Bloomberg not to lick his “dirty” fingers, seeming to make a joke referencing the growing coronavirus threat.

"Mini Mike, don’t lick your dirty fingers. Both unsanitary and dangerous to others and yourself!" Trump said in the tweet.

Earlier on Tuesday, the president said Super Tuesday will be "an interesting evening of television," but has yet to comment on the contests that have been called -- or on the sole contest Bloomberg has been projected to have won so far, American Samoa.

7:02 p.m. Sanders campaign says 'political establishment' has chosen Biden as their candidate

In a fundraising email sent Tuesday evening, the Sanders campaign responded directly to the developments in the presidential race over the past few days.

"The political establishment has chosen their candidate," the email read. "It's Joe Biden. And they're lining up behind him in an effort to derail our momentum in this race."

Although Sanders attacked Biden at a rally in Minnesota Monday night, he did not directly reference the former vice president's recent endorsements from former Mayor Pete Buttigieg, Sen. Amy Klobuchar and former Rep. Beto O'Rourke.

The campaign said it will need "an incredible amount of resources" to win the states following Super Tuesday.

"We need a lot of donations to stay on track to win," the campaign said in the email. "Because after tonight's results, we expect super PAC spending will increase dramatically in order to defeat us."

Seventy-five percent in Vermont were in favor of replacing all private health insurance with a single government plan, the most in states with exit polls today or in any previous stated -- a signature issue for Sanders and Warren alike.

Sixty-two percent would rather see the Democratic Party nominate a candidate who can beat Donald Trump versus 35 percent for one who agrees with them on major issues. Among those who cared more about electability, 46 percent cast their vote for Sanders while 29 percent went for Biden.

6 p.m. Democratic presidential candidates blast Trump administration on coronavirus response

Meanwhile, even amid Super Tuesday voting, the health threat and economic repercussions of coronavirus loom large. Democratic presidential candidates are unanimously condemning the Trump administration's handling of the outbreak. In turn, President Donald Trump has accused the Democrats of "politicizing" the issue, characterizing it as "their new hoax."

Although every Democratic presidential contender has attacked the administration for its response, only two candidates, Sen. Elizabeth Warren , D-Mass., and former New York City Mayor Michael Bloomberg, have offered formal plans to combat health crises, including COVID-19.

5:25 p.m. Voters in several states weigh in on having a self-proclaimed Democratic-Socialist on the ballot

There's a "democratic socialist" on the ballot, Sanders, and exit polls in five states asked voters if they have a favorable or unfavorable opinion of socialism. Answers varied, from a high of 62% favorable in Maine to a low of 47%in Tennessee, given currently available results.

According to ABC News reporting, 57% of Democratic voters in preliminary exit poll results from Texas have a favorable opinion of socialism.

Texans come in ahead of North Carolina and Tennessee, behind Maine, in receptivity to socialism.

Sanders has been targeted for his Democratic socialist views -- which include tuition-free college and Medicare for all. He has made the argument that democratic socialism is "less radical than characterized by opponents," and also says it's the easiest way to differentiate his campaign from Trump.

"I think it's going to be incredibly more difficult," Biden said in the exclusive interview.

5:15 p.m. How much could late-breaking events sway results

With early voting going on for a good while in most states, the potential influence of late-breaking events is an open question – particularly, former Vice President Joe Biden's win in South Carolina and former South Bend, Indiana Mayor Pete Buttigieg's and Minnesota Sen. Amy Klobuchar's decisions to withdraw from the race and endorse Biden. In preliminary exit poll results, anywhere from 31% in Tennessee to 47% in Oklahoma and Virginia alike said they finally made up their minds just today or in the last few days.

Racial and ethnic groups are worth watching at the state level, ABC News' Director of Polling Gary Langer points out. Turnout among blacks should be important given their vast support for Biden in South Carolina, where they accounted for 56 percent of primary voters and backed Biden over Sanders by 61-17%. Preliminary results tonight find black turnout highest in Alabama 44%, North Carolina 27%, Virginia 27% and Tennessee 26%.

Hispanics accounted for just 5 percent of voters in the early states overall, rising to 17 percent in Nevada. They're expected to account for many more voters in two states – Texas 32% in 2016 and California 30% in 2008, the last year for which we have exit poll data. We'll update with tonight's figures as those data come in.

Before today, Hispanics voted for Sanders over Biden by 41-20% overall, and by 50-17% in Nevada, where they were particularly young, 55% younger than 45 and supportive of single-payer government health care, two strong Sanders groups.

5:12 p.m. Here's some math to ponder

As ABC News Deputy Political Director MaryAlice Parks writes: "On Tuesday night alone, more than 30% of all of the Democratic Party's pledged delegates are up for grabs in some of the largest states in the union: California has 415 delegates, Texas has 228. Virginia and North Carolina are also voting, both of which have double the number of delegates compared to South Carolina. When the dust settles from the Super Tuesday states, 1499 delegates will have been awarded."

With so much of the delegate pool at stake in one night, will a single candidate walk away with a lead in delegates that is hard to catch or will the math shake out to show a great divide that could take months to heal and process?
