“I want to confess that I did not know your name on Monday,” Stephen Colbert told his guest, Alexandria Ocasio-Cortez, on CBS's “The Late Show with Stephen Colbert” on Thursday.

The 28-year-old Hispanic woman from the Bronx, laughed and didn’t break stride: “Most people didn’t,” she says.

Ocasio-Cortez beat 10-term incumbent Joe Crowley in the Democratic primary for the 14th Congressional District of New York on Tuesday. Crowley, the fourth-ranking Democrat in the House of Representatives, was expected to replace Nancy Pelosi as the minority leader. If Ocasio-Cortez goes on to win the seat in Congress, which she is expected to in her overwhelmingly Democratic district, she will become the youngest woman ever elected to Congress.

Ocasio-Cortez describes herself as a Democratic Socialist, and she explained what that means to her to Colbert.

“So for me, Democratic Socialism is about ... really the value for me is that I believe that in a modern, moral and wealthy society, no person in America should be too poor to live. That’s what I feel,” Ocasio-Cortez says.
