The Sanders campaign has had a galvanizing effect for many people, on social media and in real life. On Tuesday, Hillary Clinton claimed the Democratic nomination. In a speech after her victory in New Jersey, Mrs. Clinton noted the "milestone" the country had reached — and implored supporters of Mr. Sanders to join her. Those supporters have to figure out if that is what they'll do. In their own words, here is where Mr. Sanders’s most dedicated fans plan to take the “political revolution” next.

In conversations I had with more than a dozen Sanders supporters, many of them told me they were either disillusioned with or apathetic toward politics before this campaign. Mr. Sanders, a 74-year-old democratic socialist from Vermont, energized them unlike any candidate before. Now, they’ll either resign themselves to voting for Hillary Clinton, redirect their efforts to local campaigns or drop out again.

While a few die-hard Sanders supporters have vowed that it’s “Bernie or bust,” a Quinnipiac University poll from late May found that three-quarters of Sanders supporters would vote for Mrs. Clinton if it came down to a Donald Trump-Hillary Clinton race in November. Alex Sheehan, 29, a digital media entrepreneur in New York, said he thought that when faced with the prospect of a Trump presidency, most Sanders supporters would end up voting for Mrs. Clinton — and “If not, we deserve the catastrophic failure that follows,” he said.

“I’ve said it in jest that if it’s Hillary versus Trump, I will go into the voting booth and Snapchat myself voting for Trump for performance art. But I wouldn’t really do that,” he said. He paused. “Maybe I am a Bernie bro!”
