Top House Democrat Joe Crowley stunned in primary upset from progressive challenger

Progressive challenger Alexandria Ocasio-Cortez defeated incumbent Rep. Joe Crowley, D-N.Y., Tuesday night, delivering the greatest primary upset of the 2018 cycle to date.

Ocasio-Cortez, 28, bested the 10-term congressman in the primary for New York’s 14th District, all but assuring her a November victory in the Democratic stronghold. Crowley’s stunning loss echoes the 2014 defeat of House Republican Majority Leader Eric Cantor at the hands of a previously unknown college professor named Dave Brat.
