Summary: Angela Sherpa could hear fireworks on the Fourth of July, but she couldn’t see them. The 22-year-old activist from Queens spent her holiday with dozens of other volunteers inside a co-working space in Bushwick, sorting paperwork and looking up voter registration information. The night before, her chosen candidate in a contested primary for Queens district attorney, public defender Tiffany Cabán, had fallen behind Borough President Melinda Katz by a razor-thin margin of just 20 votes.
