Ocasio-Cortez, Once an Outsider, Takes Center Stage at Convention

Four years ago, Democrats allotted Representative Alexandria Ocasio-Cortez of New York a scant 90 seconds to speak at their convention. She used it to symbolically nominate Senator Bernie Sanders for president and never mentioned Joseph R. Biden Jr.’s name.

So when Ms. Ocasio-Cortez took the convention stage on Monday night in Chicago shortly before Hillary Clinton, her prime-time speaking slot offered a vivid display of how far the Democratic Party and the leader of its progressive wing have moved to embrace each other since 2020.

Greeted with chants of “A-O-C,” Ms. Ocasio-Cortez, a democratic socialist who made her name by taking on the Democratic establishment, delivered an affectionate tribute to Mr. Biden, laced into Donald J. Trump and forcefully endorsed Vice President Kamala Harris as a champion of working Americans.

“We know Trump would sell this country for a dollar if it meant lining his own pockets and greasing palms of his Wall Street friends,” Ms. Ocasio-Cortez said. “And I, for one, am tired of hearing about how a two-bit union buster thinks of himself as more of a patriot than the woman who fights every single day to lift working people out from under the boots of greed trampling on our way of life.”

She added: “The truth is, Don, you cannot love this country if you only fight for the wealthy and big business.”
