Winners and losers from the South Carolina Democratic primary
WINNERS
Hillary Clinton: No, this win was not unexpected, but it is still a win for Clinton — and it appears to be an absolute drubbing. She has now won two straight states, and she is clearly the momentum candidate heading into Super Tuesday — which is, after all, just three days away...
Black voters: Eight years after South Carolina sent Barack Obama further on his way to becoming the first black president, black voters sent a message Saturday that was loud and clear: We aren't going anywhere. Early exit poll numbers suggest the black share of the electorate could hit a new record — about 6 in 10 voters in Saturday's primary. That would exceed even the percentage in 2008...
LOSERS
Bernie Sanders: We pretty much knew this wasn't going to be close, but it turned into a disaster for Sanders. Yes, it's one state, but Sanders had one task here: To beat expectations when it comes to black voters. He didn't do that -- at all. He lost their votes a whopping 87-13, according to the most recent exit polls... And it's not just that black voters like Clinton better; they didn't seem to trust Sanders either. Just 52 percent said they would trust Sanders to handle race relations. Nearly 9 in 10 said the same of Clinton.
Young voters: ...Despite tens of thousands of people showing up to Sanders rallies, and young people favoring him overwhelmingly so far, they just aren't showing up to vote like he needs them to. Fewer than 1 in 6 voters in South Carolina were under the age of the 30. And it follows a pattern of young people just not giving Sanders the turnout he needs...

... and in spite of all the moaning and wailing about how pollsters used historical data and "weighted" the responses of older voters to count more than the responses of younger voters, we can now see that THE POLLSTERS WERE CORRECT!
The polling "raw data" wasn't accurate. The online clicky-clicky multi-vote polls where all-ages and all countries are welcome to participate weren't accurate either.
Outliers make for exciting headlines and energetic threads, but the trend-lines of multiple polls have been telling the true story all along. (Within the margin of error, as they say.)
