But interviews with nearly 50 left-leaning young people in four battleground states — Texas, Pennsylvania, Nevada and Michigan — reveal a deep skepticism toward party politics, and the Democratic Party. Young voters say Democrats haven’t proved they can address the major challenges faced by millennials and Gen Z. They want candidates who take them seriously — and who can offer up the detailed policy plans to prove it.

In conversation, these voters say they’re attracted to the ambitious policies of Sens. Bernie Sanders (I-Vt.) and Elizabeth Warren (D-Mass.), though many are undecided…

Sebastian Solove, a 28-year-old doctor in Philadelphia, has similar critiques. He is sick of Democratic leaders such as House Speaker Nancy Pelosi (Calif.) forcing younger, more liberal members of Congress to slow down on their calls for impeachment and action on climate change. He wants to see the party fully embrace the “moral high ground” on issues such as universal health care.

That’s why he’s supporting Sanders in the primary. “I like the ‘no middle ground,’ ” he said. “Whether it’s climate change or corporate welfare, we’re all sick of it. This economy is not working for normal people.”
