29-year-old Alexandria Ocasio-Cortez made history on Tuesday by becoming the youngest woman ever to be elected to Congress.

She won 78% of the vote in the midterm elections on Tuesday, according to The New York Times. She will represent New York’s 14th congressional district.

Ocasio-Cortez, a self-declared Democratic socialist, beat veteran Democratic Rep. Joe Crowley in New York’s congressional primary election in June in a shocking upset within the Democratic Party.

Just a year ago, the political novice had been working as a bartender to help support her working-class family.
