Super Tuesday results: Biden sweeps the South, Sanders strong in the West

As Super Tuesday -- the single biggest day of voting -- came to a close, the candidates competed across 15 contests for a treasure chest of delegates, which were awarded across geographically and racially diverse parts of the country.

The stakes could not be higher as Democrats faced a significant turning point in the 2020 presidential race and were 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 were up for grabs. Results in delegate-rich California are still being calculated.

Here's how the day unfolded.

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 campaign asked for polls to remain open until 10 p.m. (PST) and to offer provisional ballots to any voters who arrived at the polling sites after 8 p.m.

KABC reported that the U.S. District Court didn't schedule a hearing on the complaint filed by the Sanders' campaign before 8 p.m.About 90 minutes after the polls had closed Logan tweeted a reminder to voters in line to stay there in order to cast their ballots.

Moore said there are still long lines of people waiting to submit their ballots across the state.

As votes continued to come in from Texas, ABC News' Chief National Affairs Correspondent Tom Llamas said the margin of votes between Sanders and Biden was thin.

"All our sources from the law enforcement and intelligence community say no malicious activity of note, and no real disinformation in terms of a spike that they had been looking for," said ABC News Chief Justice Correspondent Pierre Thomas.

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.

Some misleading robocalls were reported in Texas. In the calls, the people were told to vote on the wrong day, but the senior CISA official says that those types of messages occur frequently on Election Day.

With his wins tonight, Christie said that the former vice president should expect more scrutiny in the coming weeks. "I think this is going to turn again and Biden's got to be ready," he added.

"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."

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.

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.

ABC News' Arielle Mitropoulos reports here.

In turn, President Donald Trump has accused the Democrats of "politicizing" the issue, characterizing it as "their new hoax."

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.

ABC News Chief Anchor George Stephanopoulos questioned Biden on whether or not he believes a Democratic candidate with socialist beliefs could defeat Trump in early February.

"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.

5:13 p.m. Anger at Trump unites Democrats

While divided in their vote preferences for the party's nominee, Democratic voters are united in dissatisfaction - and for some, even anger - with the Trump administration.

5:13 p.m. Racial and ethnic groups are worth watching at the state level

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?
