(INSIDE STUFF: The Redikers’ social campaign is being managed by Leonard McBain, elegant publicist and society arbiter of New York’s plush El Morocco, where the snootiest people on earth gather. Leonard has steered royalty before. He could do marvels for Tawhida.)

Since the old aristocrats died or went into hiding, it is easier to get into Washington’s society columns, if you care to horn in with inferior white trash.

Almost anyone, including justices of the United States Supreme Court, will go to any party to which they are invited. Many who aren’t invited will also show up. The trick nowadays is to entertain lavishly and often, and sooner or later the papers will have to write about you, because there is nothing else to write about.

Ambitious hostesses buy the “Social List of Washington, D.C.,” and invite names from it at random. The odds are 90 percent will show up, but the odds are as high that 95 percent of the 90 per cent aren’t social. This list competes with the standard “Social Register.” It contains most of the names in the latter, plus an amplification consisting of prominent politicians and diplomats. It is published by Carolyn Hagner Shaw. Mrs. Shaw told us a “board” selects the candidates for entry in the book. The board, however, is highly secret. One Washington newspaper insists it is as mythical as the balanced budget. Mrs. Shaw claims no one ever tells her why a name is added or dropped.

If you thought Maj. Gen. Harry Vaughan was part of the crème de la crème of the Washington social whirl, you’d better change your mind. He isn’t any more. Not if you take the word of Mrs. Shaw. She omits the military aide to the President from her fancy green directory of the socially prominent. Mrs. Shaw doesn’t know why General Vaughan isn’t socially correct any more. She blamed it on the anonymous board.

About 200 who sought to make the list were turned down. Again no reasons given. Many bought copies at 12 bucks, hoping to see their names in. They didn’t.

However, Guy George Gabrielson and William Marshall Boyle, respective chairmen of the Republican and Democratic National Committees, were among the new names added this year. The book also has the dernier cri on what to do about cards. They should not be left at Blair House, but given to the guard at the northwest gate of the White House.

“A courtesy call should be made on the President and his family once a year. This is a mark of respect that should not be neglected.” (This was before two Puerto Rican enthusiasts tried it.)

Mrs. Shaw reminds her readers “During World War II, formal observance of the conventional days set aside for leaving cards on various officials was canceled. A return to formal recognition of these traditional days has yet to take place, and it is doubtful that it will ever again become obligatory to leave cards on certain days.”

As to protocol, it notes: “It is well to remember personal friendships do not count. The rank of one’s guest must be the deciding factor.”
