The past month has delivered a series of devastating blows to the progressive soul. In late June, in the span of 24 hours, the conservative majority on the Supreme Court upheld President Trump’s travel ban and undercut public-sector unions, the latter of which was followed almost immediately by the announcement of Justice Anthony M.

Nonetheless, Ocasio-Cortez spent months knocking on doors in Queens and the Bronx with a platform that includes tuition-free college, a federal jobs guarantee, a green New Deal, abolishing Immigration and Customs Enforcement, and an unapologetic rejection of the military-industrial complex. She won by 15 percentage points.
