NEW YORK, Wednesday, Nov. 4--Robert Kennedy declared victory here this morning, but the victory was not as overwhelming as he had hoped.

In an enormous win, which swept the Republican party out of both houses of the state legislature, President Lyndon Johnson carried the majority of the New York Democratic ticket into Albany.

Even before victory was certain, Robert Kennedy received the congratulations of admirers. The politicians, family friends, and celebrities who crowded in to see him included Mayor Wagner, Governor Harriman, Arthur Schlesinger, Jr. '38 and Mariene Dietrich.

As predicted, Keating benefited by a spectacularly large number of split tickets. In many of New York City's Jewish areas, he ran almost even with Kennedy. But upstate Kennedy, although trailing Johnson, managed to better the usual Democratic vote.

Democrats gained six additional House seats in New York's Congressional delegation. One Kennedy advance man, when victory appeared certain, began whistling "Hall to the Chief."

Congressional candidates who strongly supported Goldwater, like Rockland County's Katharine St. George, seemed destined for defeat early this morning. Manhattan's handsome John Lindsay, however, who sedulously avoided affiliation with Goldwater, won overwhelmingly.
