AOC’s power comes from her outsider status. Can that endure?

She spoke loudly and with confidence, gesticulated broadly, and returned, several times over the course of her seven-minute remarks, to the struggles of working families. Alexandria Ocasio-Cortez, the congresswoman from New York and standard-bearer for the post-Bernie Sanders US left, may have been an unlikely choice for a lengthy primetime speech at the Democratic national convention’s opening night. The last time she spoke at the Democratic convention, in 2020, she was given just a minute and a half, in which she indicted the party establishment from the left and endorsed Sanders’ campaign for the nomination, which by then had failed.
