Left-Wing Democrats Wait on AOC’s Decision as They Look to 2028 Election

For the last decade, Senator Bernie Sanders of Vermont has been running for president, planning a run for president or pushing former President Joseph R. Biden Jr. to adopt more progressive policies.

But now, as Democrats find their legal and fund-raising institutions under attack from the Trump administration, their base voters furious at their congressional leadership and their party’s popularity at a generational low, progressives are also staring down the prospect of a post-Bernie future.

A movement politician with a large and devoted base of supporters, the 83-year-old Mr. Sanders has signaled that he does not intend to run for president again. The question now is who will lead the network he built from scratch into the next presidential election and beyond.

Interviews with nearly 20 progressive Democrats about the left wing’s future revealed a faction that sees the ideas Mr. Sanders has championed — reducing the power of billionaires, increasing the minimum wage, focusing more on the plight of workers — as core to the next generation of mainstream Democratic politics.

Though there is little agreement about who will emerge to guide progressives into a post-Sanders era, virtually everyone interviewed said there was one clear leader for the job: Representative Alexandria Ocasio-Cortez of New York.

And it just so happened that Mr. Sanders and Ms. Ocasio-Cortez spent three days last week on a “Fighting Oligarchy” tour through Arizona, Nevada and Colorado. In Denver, they drew 34,000 people, what Sanders aides said was the largest crowd of his career. Neither has so much as obliquely referred to the torch-passing nature of their trip, and in an interview, Mr. Sanders declined to answer questions about whether Ms. Ocasio-Cortez, 35, would inherit his mantle. But the subtext of their travels appears clear.
