Speaking at the National Urban League Annual Conference on Thursday, Booker sought to undercut Bidenâs strong poll numbers with black voters, a core constituency in the Democratic primary and a current key base of his support.
The speech followed days of attacks from Booker on Bidenâs new criminal justice reform plan, in which Booker highlighted Bidenâs role in championing the 1994 crime bill that experts link to mass incarceration, dubbing him âthe proud architect of a failed system.â
âIt is easy to call Donald Trump a racist now; you get no badge of courage for that,â Booker said. âThe question is, what were you doing to address structural inequality and institutional racism throughout your life? Donât just tell us what youâre going to do. Tell us what youâve already done. Donât just tell us youâre going to be a champion for our communities when you become president, if you havenât been a champion already.â
Biden and his campaign, meanwhile, have increasingly criticized both Booker and Harris in the lead-up to next weekâs debate, forcefully defending Bidenâs record on race and openly drawing contrasts on issues ranging from health care to policing. Bidenâs willingness to engage his rivals comes after Harris tore into his record of opposing busing initiatives on the debate stage last month, dealing him his most significant blow of the campaign to date.
Virtually everyone in Bidenâs campaign, from the former vice president on down, subscribes to the idea that he can no longer seek to stay above the Democratic fray on the debate stage, a posture he had tried to maintain in the early weeks of his campaign.
âIâm not going to be as polite this time,â Biden said at a fundraiser in Detroit on Wednesday. When an attendee told him that clashing with Booker and Harris now could make him a stronger general election candidate, Biden said: âIf they want to argue about the past, I can do that. I got a past Iâm proud of. They got a past thatâs not quite so good.â
The confrontation on race and inequality between the candidates has been building for weeks and appeared to be approaching a boiling point Thursday. Ever since Booker dispensed with the primaryâs early-stage niceties and demanded Biden apologize for his warm remarks about working with segregationists in the Senate, he and Harris have gone on the offensive by aggressively denouncing Bidenâs record on race.
By highlighting Bidenâs opposition to school busing, his support for the crime bill and other aspects of his long career in Washington, Harris â who later had to clarify her current stance on busing â and Booker have sought to portray their rival as having been on the wrong side of issues and developments affecting black Americans for decades. But polls have shown Biden with consistent, and sometimes commanding, leads among African American voters at this stage in the race.
Though Booker never mentioned Biden by name Thursday, his speech amplified the critique, making the case that Bidenâs record on issues like criminal justice could hamper his ability to energize African American voters, whose turnout will be critical if the Democrats wish to defeat President Donald Trump next year.
âI want to talk about what people often mean when they say or ask, âIs someone electable,â â Booker said. âBecause most of the time when somebody is asking about electability, theyâre not asking about the African American voters who make up the most reliable constituency of the Democratic Party. And thatâs a problem.â
A day earlier, Biden swung back at Bookerâs criticisms by making his own arguments against Bookerâs record while he was mayor of Newark, New Jersey.
âHis police department was stopping and frisking people, mostly African American men,â he said of the Newark Police Departmentâs record of conducting improper stops under Bookerâs watch.
His campaign also sent a lengthy statement to reporters Wednesday afternoon responding to Bookerâs criticisms of Bidenâs record. âIt is Senator Booker, in fact, who has some hard questions to answer about his role in the criminal justice system,â the statement said.
The return volley from Bidenâs campaign elevated Booker, a candidate who has struggled in the polls for months, as the back-and-forth created a drumbeat of media coverage leading into next weekâs debate. And the aggressive response from Biden further freed Booker to take more direct aim at Biden in the debate Wednesday, when he and Harris will be standing on either side of him.
Less than an hour after Booker made his comments about electability, Kate Bedingfield, the Biden campaignâs communications director, returned fire, sending a tweet with photos of two polls that indicated Bidenâs support among black voters far surpassed Bookerâs.
Later Thursday, Monmouth University released a new poll out of South Carolina that bolstered that case. The survey showed Biden with a wide lead in the state, one of the first to vote next year, thanks in large part to his support from 51% of black voters there. Only 2% of black voters said they would vote for Booker.
At the same time, Harrisâ decision to highlight Bidenâs stance on school busing and integration at the June debates also gave her a significant boost in recent polls that was propelled in part by black voters. In the Monmouth poll, Harris finished a distant second behind Biden, drawing support from 12% of black South Carolina voters.
Biden has said he felt blindsided by Harrisâ questioning, a point he reiterated in a radio interview that aired Thursday morning on âThe Tom Joyner Morning Show.â
âI thought we were friends,â he said. âI hope we still will be.â
