Carter aides dragged their feet and it took a nudge or two from House Speaker Thomas S. "Tip" O'Neill and California's Sen. Alan Cranston before former Los Angeles city council-woman Rosalind Wyman was finally named to the National Endowment for the Arts last May.

Now it looks as if President Carter may have lost Wyman to the campaign of Sen. Edward M. "Ted" Kennedy.

Roz Wyman is one of the Democratic Party's major fund-raisers, a distinction she shared with her late husband, California Democratic State Chairman Eugene L. Wyman, who died in 1973.

The Wymans have always been close to the Kennedys. In 1956, they supported Sen. John F. Kennedy in his unsuccessful bid for the vice presidential nomination at the Democratic Convention.

She worked so hard for JFK in Chicago that year that she was hospitalized with a miscarriage. She worked for him again, in 1960 and for his brother, Sen. Robert F. Kennedy, during his 1968 presidential campaign.

Wyman, closely connected to a number of Jewish causes, has not yet formally announced for Kennedy. But she is known to have been telling other Democratic fat cats in California that they should tell President Carter they don't think he can win.

Barry Landau, the New York publicist who is one of White House chief of staff Hamilton Jordan's accusers in the Studio 54 coke-sniffing allegations, has fallen on hard times.

Landau, deserted by a lot of his fair-weather friends after he became embroiled in the Jordan affair, was evicted from his apartment last week after he was unable to pay back rent.

He moved into the Westbury Hotel for a few days and then moved out.

He says he told the management to "send me the bill in care of Roy Cohn."

Cohn was his lawyer, Landau says, before Cohn was hired to represent the owners of Studio 54.

At the dedication of the John F. Kennedy Library in Boston over the weekend, Joan Kennedy and her daughter both wore the same outfits two days in a row for both the dinner on Friday and the ceremony on Saturday. Mrs. Kennedy never changed her yellow ultra-suede coat. Kara wore heelless wooden clogs, a black skirt with a zig-zag hemline and a boy's athletic sweater . . .

A friend of Jacqueline Kennedy Onassis who was at the ceremony in Boston with her says that in New York yesterday no one was talking about "anything else" but the "royal" displeasure the former first lady expressed visibly when President Carter kissed her. "It wasn't Queen Victoria," says the friend. "It was pure Queen Mary" . . .

Billy Carter's wife, Sybil, apparently doesn't dare do it when her mother-in-law "Miss Lillian" is watching, but Sybil apparently breaks up the neighbors at the Best Western bar and grill with an imitation she does of the way President Carter eats in public . . .

. . . The Carters saw "The Onion Field" at Camp David over the weekend . . . D.C. Mayor Marion Barry and his wife Effi never seem to make the Polo Club at the same time. She's in there night after night, with friends, dancing till the weekends. He was there on Saturday with one group early in the evening and she was there later with another. A spokesman for the mayor says the Barrys go lots of places separately. "She's a career woman with a schedule of her own," the aide said.

. . . Tongsun Park's favorite decorator, Paul Enten, who did all his houses and clubs and was supposed to do his new town house in London, has been trying to find a ghost writer to help him with a book. The subject is unknown.
