Many feel alienated by the Democratic Party. They may want unity, but not if it means a stamp of approval for a political status quo they believe is fundamentally flawed and needs to be fixed.

“Just pack up your revolution and go home? Really? That’s not going to happen,” said Tara Margolin, a 50-year-old Sanders supporter and self-described Democrat who lives in Los Angeles.
