ALBANY, N.Y. (AP) _ A fourth statewide poll in less than three weeks has found Hillary Rodham Clinton in a very close Senate race with Republican Rep. Rick Lazio.

A CBS News/New York Times poll released Monday had Clinton with a slight lead over the congressman from Long Island. The first lady was backed by 44 percent of likely voters surveyed to 39 percent for Lazio. Seventeen percent were undecided.

The telephone poll of 1,187 likely voters was conducted from June 4 through Saturday and had a margin of error of three percentage points.

A CBS News/New York Times poll out in April had Clinton leading Mayor Rudolph Giuliani, 49 percent to 41 percent, with 10 percent undecided. Giuliani quit the race May 19 to deal with his prostate cancer.

Since Lazio joined the race, polls have either shown Clinton with a small lead or the two candidates essentially tied.
