The powerful Culinary Union, which opposes Sanders’ Medicare for All plan and spent the final weeks of the campaign in a high-profile fight with his campaign, was supposed to weaken him. And yet the Sanders’s ranks were speckled with red-shirted Culinary members. (Overall, Sanders won 34% of caucus-goers from union households, besting all of his rivals.)

Sanders wasn’t supposed to be able to break through with black and brown voters, but the group was racially and ethnically diverse. (Sanders won 27% of African Americans and 53% of Hispanics across the state.) The Sanders movement is supposed to be limited to those crazy college kids who don’t remember socialist as a slur. But there were plenty of older Sanders backers at the Bellagio chanting “Bernie” along with their 20-something comrades. (Sanders won every age category in the state except Nevadans over 65, which he ceded to Joe Biden.)…

He was said to have a ceiling of 30% or so. Remarkably, against a much larger field of candidates Sanders is poised to come close to the same level of support as he did in 2016 in a one-on-one race against Hillary Clinton, to whom he lost 47%-53%. (He was at 46% with a quarter of precincts reporting as of this writing.) He was said to be unable to attract anyone outside his core base. But he held his own with moderate voters (22%) and won across every issue area except voters who cared most about foreign policy, who went with Biden.
