Alexandria Ocasio-Cortez is bringing some young blood to U.S. Congress…

The 29-year-old Puerto Rican politician and New York Democratic congressional nominee has won her general election race soundly, becoming the youngest woman ever in Congress.

Ocasio-Cortez, who turned 29 last month, will inch out the previous holder of the distinction, New York Democratic Rep. Elise Stefanik, who was elected to Congress at age 30.

Ocasio-Cortez defeated New York Democratic Rep. Joe Crowleyin the primary election earlier this year. The victory was considered a major upset and elevated Ocasio-Cortez onto the national political stage.

Crowley, the No. 4 Democrat in the U.S. House of Representatives, was seen as a potential speaker one day. His loss effectively handed the seat to Ocasio-Cortez, a Latina who has become a key left-wing voice.

Ocasio-Cortez ran unabashedly to Crowley’s left in the New York City district and previously worked as an organizer on Vermont independent Sen. Bernie Sanders‘ presidential campaign. She is a member of the Democratic Socialists of America.
