The overriding implication in Jack Anderson and Dale Van Atta's column ''Puerto Rican Interests Court Hill'' {Metro, Oct. 19} is that members of the Democratic Party, which favors the existing commonwealth status rather than statehood or independence in a pending referendum, are somehow guilty of ''throwing money at some of the most skilled lobbyists in Washington'' in efforts to influence the proposed status vote. The column practically admits that the origin for such speculation is ''sources in the statehood movement.''

But these same ''sources in the statehood movement'' forgot to mention that President Bush has thrown the full weight of the White House behind subtle and not-so-subtle efforts to influence the people of Puerto Rico to favor statehood. It was President Bush in his first message to Congress who raised the status issue to new levels when he expressed his preference for statehood and called upon Congress to consult the people of Puerto Rico on the matter. It was President Bush who sent two of his top aides, Andrew Card and Chase Untermeyer, to Puerto Rico last summer to actively campaign for statehood, even though it should have been obvious that strict neutrality should have been observed by the White House.

Perhaps Mr. Anderson should also report that Secretary of the Interior Manuel Lujan recently appeared at a pro-statehood rally in Puerto Rico, giving more weight to Bush administration attempts to influence the plebiscite. Perhaps Mr. Anderson should also not that the pro-statehood movement has its share of lobbyists in Washington, of which Harry MacPherson is perhaps the best known. JAIME B.
