In status-conscious Washington, where low-numbered automobile tags are a cherished symbol of rank, Daisy P. Moore is about to be bumped from No. 4 - but not without a fight.

Daisy P. Moore is not your ordinary VIP. She is the wife of D.C. City Council member Douglas E. Moore (D-at large), a man not known for calm disposition or silent tongue.

Officially informed yesterday that tag No. 4 was going to be reassigned to someone else. Moore distated a searing memorandum accusing Council Chairman Sterling Tucker of overstepping his power and taking the tag away.

"Historically and currently, you have no right to that tag, and it remains in my possession (to assign)," Moore wrote, adding:

" . . .You are setting a dangerous precedent . . .And in fact, the next (council) chairman may wish to take all the low tag numbers, if not more."

Moore did not mention that he has announced his candidacy for council chairman to succeed Tucker, who is one of four announced aspirants for the Democratic nomination for mayor.

Tucker said through a spokeman that he had no knowledge of the reassignment of tag No. 4 or to whom it might go. "It will be taken care of . . . If Douglas has a right to have it, he will have it," Tucker said.

In auto-tag sequence, Daisy Moore ranks only below No. 1, Mayor Walter E. Washington, No. 2, Tucker, and No. 3, City Administrator Julian R. Dugas.

Under current practice, the assignment of the major's office and council members. Douglas Moore said the assignment No. 4 is a legacy of past years when the mayor controlled all the tags, and Moore was the mayor's most outspoken ally on the council.

Moore said he gave No. 4 to his wife because his own car carries a special City Council tag.

Moore said his wife really doesn't care about having the prestige of a low number on her two-year-old German-made sedan. Asked why he decided to make such a fuss about losing it, he replied: "It's the principle."
