SPRINGFIELD, Va.—On a wind-whipped 36-degree Saturday, young people turned out in droves for Sen. Bernie Sanders’ campaign rally in northern Virginia. Dozens of 20-somethings wearing nametags designating them as “Bernie volunteers” helped check in 6,000 attendees at the St. James Sports, Wellness, and Entertainment Complex. With two hours to go before their candidate arrived, attendees chatted excitedly, heads and blue-and-white Bernie signs bobbing along to the music playing over the loudspeaker. They cheered as each new group of people trickled in from outside.

Sen. Elizabeth Warren of Massachusetts is ending her bid for the Democratic presidential nomination Thursday after failing to win a single caucus or primary, including Tuesday’s contest in her home state. Armed with policy plans intended to pull the candidates to the left, Warren initially earned front-runner status in the race last fall. But the initial excitement over her campaign never translated to broad appeal.

Former Vice President Joe Biden made a strong comeback in the race for the Democratic nomination for president, winning Super Tuesday contests in Alabama, Arkansas, Maine, Massachusetts, Minnesota, North Carolina, Oklahoma, Tennessee, Texas, and Virginia. Rival Sen. Bernie Sanders, I-Vt., won delegate-rich California, along with Colorado, Utah, and his home state of Vermont.

Former Vice President Joe Biden had a strong showing on Super Tuesday, winning the Democratic primaries in Virginia, North Carolina, Alabama, Oklahoma, Tennessee, Minnesota, Arkansas, Texas, and Massachusetts, where he defeated Sen. Elizabeth Warren in her home state. He was in the lead in Maine, where the election was still too close to call early Wednesday.

In his classic book about the volatile presidential election of 1968, journalist Theodore White compared Republican Richard Nixon to Ebenezer Scrooge’s partner Jacob Marley: “Political clerks, clergymen, undertakers, and mourners had all signed the register. Nixon was as dead as a doornail.”

Except he wasn’t.

Democratic candidates are battling for 1,357 delegates in Super Tuesday contests across the nation. They need 1,991 to secure the party’s nomination and face President Donald Trump in November.

The first openly gay presidential candidate ended his campaign on Sunday. “We must recognize that at this point in the race, the best way to keep faith with those goals and ideals is to step aside and help bring our party and country together,” Pete Buttigieg told supporters in South Bend, Ind., where the Democrat served as mayor until recently.
