Sen. Bernie Sanders won the primary Tuesday night, with former South Bend, Ind., Mayor Pete Buttigieg not far behind and an unexpectedly strong Sen. Amy Klobuchar in third. Sen. Elizabeth Warren and former Vice President Joe Biden finished a distant fourth and fifth, respectively. And two candidates’ campaigns didn’t survive the night.
