Democrat Alexandria Ocasio-Cortez has defeated a little-known Republican opponent in a district representing part of New York City.
Her victory Tuesday over economics professor Anthony Pappas was widely expected after Ocasio-Cortez scored an unanticipated upset over 10-term U.S. Rep. Joe Crowley in the Democratic primary in June.
At 29 years old, Ocasio-Cortez could become the youngest member of Congress.
She is one of a handful of Congressional candidates who identified as democratic socialists.
Ocasio-Cortez has promised to try and push the Democratic party further to the left.
She supports government-paid health care for all, a $15 minimum wage, free college tuition and the abolition of the federal department of Immigration and Customs Enforcement.
