Fourteen states and one territory held nominating contests for the Democratic Party's candidate for president on Tuesday, the most pivotal day on the presidential primary calendar.

When the polls closed on Super Tuesday and results came in, it became clear that former Vice President Joe Biden had swept the Southern states, winning the primaries in Virginia, North Carolina, Alabama, Tennessee, Oklahoma, Arkansas and Texas, as well as Minnesota and Massachusetts, and had ended the night with the most delegates. Sen. Bernie Sanders came out on top in Colorado, Utah and his home state of Vermont, NBC News projected.

On Wednesday, NBC News declared Biden the apparent winner in Maine, though the race against Sanders in the state was a tight one.

More than 1,300 delegates — about a third of the total — were at play, more than on any other day in the primary season.

NBC News Exit Poll: Bloomberg fails to win over key constituencies

Results from the NBC News Exit Poll find Mike Bloomberg lagging behind Joe Biden among his core constituencies. 

Despite campaigning on his viability in the general election, Bloomberg is winning just 13 percent of Democratic primary voters who say they would prefer a candidate who can beat Trump over one who agrees with them on major issues. Bloomberg is also struggling to gain traction among college graduates, older voters, and independents — capturing about 11 percent to 17 percent of voters within each of these groups.   

Bloomberg is pulling in about one in six self-described moderate or conservative Democratic voters in the 12 Super Tuesday states where exit polling was conducted. The plurality of these voters, 42 percent, are going for Biden.

NBC News Exit Poll: Voters concerned about coronavirus support Biden on Super Tuesday

The coronavirus outbreak was on many Democratic voters' minds as they went to the polls on Super Tuesday. In five states covered by the NBC News Exit Poll — California, North Carolina, Tennessee, Texas and Virginia — just over half of primary voters said that the coronavirus was an important factor in their vote. The figure ranged from 51 percent in California to 61 percent in Texas.

Across the five states, 67 percent of voters ages 45 and over said the coronavirus was an important factor, while just 33 percent of those under age 45 felt the same. Joe Biden was the candidate of choice of nearly half of those who rated the outbreak as an important factor, followed by Bernie Sanders. 

NBC News Exit Poll: Klobuchar seen favorably by most Minnesota Democratic primary voters

Eyes are on Minnesota tonight and its 75 pledged delegates after home state Sen. Amy Klobuchar suspended her campaign on Monday and offered her endorsement to Joe Biden.

Klobuchar is well-liked. About three-quarters of Minnesota’s Democratic primary voters so far today have a favorable opinion of her. But she faced competition for the nomination from fellow moderates and she needed to make inroads among the majority liberal Democratic primary voters on her home turf. (In Minnesota, 68 percent of Democratic primary voters are liberal, and 32 percent are moderate or conservative.)

Nine in 10, or 92 percent, of those backing Biden in Minnesota tonight have a favorable view of Klobuchar. Meanwhile, 73 percent of Bloomberg voters in Minnesota, 80 percent of Warren voters and 52 percent of Sanders voters in the state see Klobuchar in a favorable light.

NBC News Exit Poll: Late-deciding Super Tuesday voters break heavily for Biden

Joe Biden is garnering nearly half the support of Democrats who picked a candidate in just the last few days before Super Tuesday, according to early results from the NBC News Exit Poll conducted in 12 of the 14 Super Tuesday states. 

Riding a wave of endorsements from former rivals and his landslide victory in Saturday’s South Carolina primary, Biden was favored by 47 percent of Super Tuesday voters who said they picked a candidate in the last few days. He left Bernie Sanders, Elizabeth Warren and Mike Bloomberg far behind with these late-deciding voters.

By contrast, Sanders built a comfortable lead over Biden, 37 percent to 25 percent, among voters who picked a candidate earlier than the last few days.

Late-deciding voters made up more than a quarter of the Super Tuesday electorate, exit poll results show.
