CONCORD, N.H. Senator Elizabeth Warren is instructing voters on what to believe. Her policy vision smacks of an academic exercise. Her advocacy style is my way or the highway, and she has displayed an elitist attitude.
In ways overt and subtle, Joseph R. Biden Jr., his campaign and his allies have begun mounting personal attacks on his most formidable rival in the 2020 primary race, portraying her as embracing a rigid, condescending approach that befits a former Harvard professor with an ambitious policy agenda.
It is a politically risky case to make against a leading female candidate, especially to a Democratic primary electorate that has so far signaled little appetite for intraparty warfare. Women historically make up a majority of Democratic primary voters, and for many, memories of attacks against Hillary Clinton in 2016 are still fresh.
The aggressive approach is also new territory for Mr. Biden, the former vice president who served for decades as a decorous senator and typically tempers rebukes of opponents with mentions of their good character.
Ms. Warren, who generally refrains from sparring with her rivals, has started to push back, denouncing criticism from powerful men who try to tell women how to behave.
The back-and-forth between the two candidates signals the start of a more combative phase of the 2020 race, with their jousting largely focused on Ms. Warrens $20.5 trillion plan to pay for a sweeping Medicare for all program. Democratic pushback against that plan has buoyed Mr. Bidens campaign, which is keenly aware of Ms. Warrens political momentum in key states like Iowa, where the first nominating contest will be held in less than three months.
After the Biden team dismissed her Medicare for all plan, Ms. Warren suggested critics were embracing Republican talking points and even running in the wrong party remarks that Mr. Biden found personally galling, advisers and allies said. He responded in a toughly worded statement and in a fund-raising appeal on Tuesday, casting Ms. Warrens response as condescending, reflective of an angry unyielding viewpoint and representative of an elitism that working- and middle-class people do not share.
He repeated versions of that argument in a radio interview and at fund-raisers throughout the week, decrying Ms. Warrens attitude in a way that struck some voters and political operatives as sexist, and others as ironic, given that he sometimes made this populist argument at his own events with big donors.
On Friday, Mr. Biden told reporters at New Hampshires Statehouse here that the next president of the United States is going to have to make sure that theyre able to get things done, pass things. He added, Going after peoples motives or instructing them on what they should believe is not the way that you get things done.
Ms. Warren, who caught up to or surpassed Mr. Biden in some polls this fall and now faces the scrutiny that comes with being a leading candidate, fired back on Friday, sending a fund-raising email with the subject line, I am angry and I own it.
Over and over, we are told that women are not allowed to be angry, Ms. Warren wrote in the message, which did not mention Mr. Biden. It makes us unattractive to powerful men who want us to be quiet.
She added: Well, I am angry and I own it. Im angry on behalf of everyone who is hurt by Trumps government, our rigged economy, and business as usual.
Asked on Saturday if she thought Mr. Biden would describe her as angry and condescending if she were a man, Ms. Warren replied, Why dont you ask him that?
The confrontation between the two leading candidates reflects the unsettled nature of the Democratic primary race, where Mr. Biden and Ms. Warren are now squaring off as the two leading candidates while she is also playing both offense and defense on Medicare for all. But just as apparent are the gender dynamics and dangers in personal attacks for a Democratic field that began with a record number of female candidates but is now dominated by three white men Mr. Biden, Senator Bernie Sanders of Vermont and Mayor Pete Buttigieg of South Bend, Ind. and Ms. Warren, of Massachusetts.
Mr. Bidens attacks, in effect if not intent, include descriptions that some voters and researchers on women and politics see as sexist tropes about female politicians: portraying them as overbearing, schoolmarmish or different from the norm.
The question is whether Biden would use the same words to describe a male professor and I suspect he would, said Gloria Steinem, the feminist leader. The larger problem is that theyre about style, not content.
His criticism of Ms. Warren troubled some voters who came to see her on the campaign trail over the weekend.
I think its sexist, Savannah Johnson, a social worker who supports Ms. Warren and who attended a town hall she held in Goose Creek, S.C., on Saturday, said of Mr. Bidens criticism.
I just dont think that hed be saying the same thing about a male candidate, she added. I think that all strong women kind of get labeled that unfairly.
Niamh Cahill, 21, a college student who also came to the town hall, said Ms. Warren would not be getting as much grief if she were a male candidate. Yeah, shes fired up, shes angry, but for a good reason, she said. There are a lot of things that are wrong in this country.
Mr. Biden often discusses his record of advocacy for womens rights by citing his championing of the Violence Against Women Act and his work combating campus sexual assault. And none of his remarks have come close to the audaciously sexist language and tactics that President Trump used against female political opponents like Mrs. Clinton and Carly Fiorina in the 2016 campaign or his offensive and demeaning language about Megyn Kelly, Stormy Daniels and the women he referenced in his taped interview with Access Hollywood.
Mr. Biden said in a CNN interview that his criticisms of Ms. Warren had nothing to do with gender. He and his allies said he was focused on debating the merits of policy and approaches to leading and governing.
As an African-American woman who serves as mayor of Atlanta, I know what sexism and racism looks and feels like and I dont see it here, said Mayor Keisha Lance Bottoms, who has endorsed Mr. Biden. When people propose these great plans, how will they be paid for? I think people expect to have real answers to that. And I think to the extent that youre touting plans I think you need to be prepared to explain it and not create distractions.
Still, for Ms. Warren, being called elitist is squarely at odds with how she introduces herself to voters. She often discusses growing up in Oklahoma on the ragged edge of the middle class and is running for president as a corruption-fighting populist. Mr. Bidens words conjured Ms. Warrens career as a Harvard law professor a title that could unsettle voters without college degrees, a demographic with which Mr. Biden is currently strong, polls show.
On the campaign trail, Ms. Warren talks about her time as a law professor but does not draw attention to her affiliation with Harvard, and she notes in her stump speech that she went to a public law school (she attended Rutgers).
On Friday, Mr. Bidens campaign issued a news release slamming her Medicare for all proposal as unrealistic, arguing, being president isnt an academic exercise. The message reminded some Democrats of how- Senator Scott Brown unsuccessfully sought to caricature Ms. Warren as an out-of-touch professor in their 2012 Massachusetts Senate race.
I dont think it will work for the Biden team, either, because first of all, her personal story is the antithesis of anything elitist, said Mary Anne Marsh, a Boston-based Democratic strategist unaligned in the presidential primary, though some of her colleagues have worked on Ms. Warrens prior races. Shes done a very, very good job consistently defining her life story.
Mr. Biden is hardly dismissing Ms. Warren as a professor. And his campaign noted that he had used words like elitist and angry to describe Republican men before. His allies are also trying to tap into increasingly vocal pushback against Medicare for all and its potential political consequences from Democrats in 2020 battleground states; House Speaker Nancy Pelosi also recently warned that such a plan, and its elimination of private health insurance, carries significant political risk.
And he is plainly uncomfortable repeating in person the fierce criticism about Ms. Warrens condescending style that he issued in his Tuesday statement. Asked directly if he felt Ms. Warren was out of touch, he replied to reporters, Im not saying shes out of touch. What Im saying is, the way to approach politics today to get things done is not to question peoples motives.
I wasnt referring to Elizabeth Warren as being elitist, Mr. Biden insisted at another point during an exchange with reporters here. I said the American people out there, they understand whats going on, and they dont like being instructed on what they should believe and what they dont believe.
In big primary fields, attackers can often damage their opponent but hurt themselves in the process. That has been the case for multiple Democratic contenders who have swung at Mr. Biden in personal terms, only to face blowback. For Mr. Biden now, the risk is especially great because he is seen by many voters as a warm and gracious figure in the party and harsh attacks could seem out of character.
Still, for some voters, the clash between Mr. Biden and Ms. Warren was illuminating more than worrisome.
I like that its personal, said Stanley Brown, 49, of Tilton, N.H., who attended a Biden event on Friday and is considering Mr. Biden and Ms. Warren along with several other candidates. They care. Its not just a canned answer.
