"Unfortunately, I think that the baby boomer generation of the Democratic Party — and it's a very large group of people — did not spend their energy on investing in the next generation, so we do not have the deepest bench,” Konst told Hill.TV’s Krystal Ball and Buck Sexton on “Rising.” 

"And not only that, we don’t have the deepest, most progressive bench even though the country is more progressive than it's ever been,” she continued.

Konst, who is now running for New York City public advocate, argued that Sanders, unlike the Democratic Party as a whole, has invested in a new crop of leaders through Our Revolution, a nonprofit formed in the wake of Sanders's presidential campaign to continue advancing progressive goals.

“The consistency and the willingness to stay progressive and really lead the party and invest in other generations, as what he did with Our Revolution, is what separates him from the pack,” she told Hill.TV.

“The organization he founded — Our Revolution — recruited candidates in every single state, in many counties, most cities have a chapter and that’s a built-in infrastructure for not just a movement but to be able to defeat Donald Trump,” Konst said.

After months of speculation, Sanders on Tuesday officially announced that he would seek the Democratic presidential nomination for the second time.

The senator, a self-described democratic socialist, has emerged as a leader of the progressive issues like “Medicare for all" that have become more widely embraced by his colleagues and fellow Democratic presidential candidates like Sen.
