The New York congresswoman Alexandria Ocasio-Cortez answered a question about potentially running for higher office in 2028 by declaring: “My ambition is to change the country.”

The Democrat delivered that remark at a political forum in Chicago on Friday amid widespread belief that she is positioning herself to run for the White House in 2028 or challenge her party’s leader in the US Senate, fellow New Yorker Chuck Schumer.

“What’s funny is they assume my ambition is a title or a seat,” the Bronx US House representative replied. “My ambition is to change this country. Presidents come and go. Senate, House seats, elected officials come and go.

“But single-payer healthcare is forever,” she added, in reference to the kind of national healthcare platform she has long supported over the private system entrenched in the US.
