A majority of likely Democratic voters, 55 percent, said they supported or leaned toward backing Ocasio-Cortez, while only 36 percent favored Schumer, Politico reported based on the poll by left-wing think tank Data for Progress.

The poll marks another setback for Schumer, who has struggled to quell intraparty backlash over his vote to advance a Republican-led funding bill to avert a government shutdown.

At least two House Democrats have openly called for his ouster, arguing that he is not doing enough to counter the Trump administration. A third Democrat said that other members of the caucus want Schumer out but "just haven't been asked directly or avoided the question."
