Booker Takes On Biden in Bid to Break Through Crowded Field Associated Press In nearly six months as a Democratic presidential candidate, Cory Booker has billed himself as many things: He's both an optimist leading with "radical love" and a fighter against political machines. He's both a supporter of "Medicare for All" and an advocate for more incremental health care policies that preserve the private insurance industry. As the New Jersey senator prepares for a pivotal turn in the spotlight at next week's debate, he's trying on a new role: Joe Biden's chief antagonist. Ahead of an expected showdown in Detroit, Booker is blasting the former vice president as "an architect of mass incarceration." Speaking to the National Urban League on Thursday, he assailed rivals whom he portrayed as latecomers to the fight against "structural inequality and institutional racism" -- implying, without mentioning Biden's name, that his opponent had embraced criminal justice reform to further his presidential candidacy. .
