First lady Michelle Obama has emerged as perhaps the most effective Donald Trump critic in the Democrats' lineup, and she's done it without ever uttering two key words: Donald Trump.
In her six campaign trail speeches for Hillary Clinton, the first lady has never said the Republican nominee's name. She's talked about "this candidate" and dedicated much of her time to a searing indictment of his words and positions. But throughout her buzzworthy takedowns, Trump remains the man who shall remain nameless.
Mrs. Obama didn't depart from her rhetorical dismissal of Trump in Phoenix Thursday. Her appearance in Arizona was a mission to crack open new territory in a GOP-leaning state polls show is now competitive.
The Clinton campaign and Mrs. Obama's staff are reluctant to discuss motives for the obvious omission. But Mrs. Obama's rhetoric shows her trying to balance her position as first lady -- a figure long viewed as out of the political fray -- while also holding little back in a race she clearly feels strongly about.
At a rally in Arizona Thursday, she referred to Trump dozens of times, but in the abstract. "When a presidential candidate threatens to ignore our voices and reject the outcome of this election, he is threatening the very idea of America itself," she told roughly 7,000 raucous supporters at the Phoenix Convention Center.
She also spoke in personal terms, suggesting that Trump's life in a Manhattan tower keeps him from seeing the humanity in people who are different from him. And that, she suggested, is why he speaks so harshly of African American communities and insults Muslims, women, people with disabilities, Mexicans, and more.
"Maybe that's why he calls communities like the one where I was raised, `hell,"' she said. "Because he can't see all the decent, hardworking folks like my parents."
Political speakers are often coached to avoid using opponents' names or titles, to deny them any measure of extra publicity or credibility.
It's a time-worn demonstration of disdain by denial, said Mary E. Stuckey, a scholar of political oratory at Georgia State University. By marginalizing him personally, Mrs. Obama also aims to marginalize what he stands for as a candidate.
It may just be coincidence, but Mrs. Obama's speech Thursday is at the downtown convention center in Phoenix where Trump issued a reaffirmation of his immigration policy proposals, which Clinton sharply opposes.
"Naming, of course, is a form of power. It defines things and makes them real," Stuckey said. "To refuse to name is also to refuse to recognize something."
But others see additional possible motives in Mrs. Obama's rhetoric.
Where previous first ladies have typically played the role of loyal spouse and burnished their husbands' records while campaigning, Mrs. Obama has taken a different tact, said Anita McBride, who was chief of staff to first lady Laura Bush.
"Her speeches have been more political," McBride said. "Her speeches at the Democratic National Convention and in New Hampshire last week were sharper, more targeted and more cutting than anything I've seen in a previous first lady."
Mrs. Obama spoke at length at the Manchester rally about the release this month of a video from a 2005 "Access Hollywood" interview, where Trump said into a microphone he did know was live, that he used his celebrity to make sexual advances on women without their consent.
In the weeks that followed, nine women have accused Trump over the past 30 years of kissing and groping them against their will.
Mrs. Obama's response was an effort to starkly refer to Trump as "this candidate actually bragging about sexually assaulting women. I can't believe I'm saying that."
Trump has made a habit of retaliating against his critics. The only time he has mentioned Mrs. Obama during the campaign has been to attempt to poke holes in her support for Clinton by reminding voters of the fierce fight for the 2008 Democratic nomination Clinton fought against President Barack Obama.
Clinton's daughter, Chelsea, has not followed Michelle Obama's example. Speaking at Arizona State University Wednesday, she sprinkled Trump's name throughout her 30-minute speech and question-and-answer session with more than 500 supporters on the campus in Tempe.
That leaves some former Obama administration staff and others suggesting that the first lady finds Trump so objectionable that she refuses to utter his name as a way of denying him credibility.
"I wonder in some ways if she finds his politics and rhetoric so distasteful she can't bring herself to say his name," said the former Bush senior aide McBride. "Clearly, there's a great deal of passion in these speeches."
