Sen. Daniel Patrick Moynihan (D-N.Y.), taking to the airwaves early in his reelection drive, has launched a $300,000 ad campaign that includes an unexpected boost from Sen. Robert J. Dole (R-Kan.).

The commercials, prepared by the Sawyer-Miller Group, tout Moynihan's achievements on such issues as salvaging Social Security, banning "cop-killer" bullets and steering highway funds to New York.

They close with a tag line of "New York's Moynihan," perhaps to counter perceptions that he has grown out of touch with the state.

In addition to the usual Democrats, one ad features a clip of Dole, on the presidential campaign trail in Iowa, crediting the New York senator with helping save the Social Security system in 1983. "I said to Pat Moynihan, 'We've got to fix it,' and fix it we did," Dole says.

The blitz comes as Manhattan U.S. Attorney Rudolph W. Giuliani is edging closer to challenging Moynihan.

One hitch, though: the Republican prosecutor says he won't run unless Sen. Alfonse M. D'Amato (R-N.Y.) finds a worthy successor -- preferably one of Giuliani's top assistants -- within two weeks.

D'Amato is said to be angry about Giuliani's ultimatum and is proceeding at his own pace in recommending a new U.S. attorney to the White House. Watch this space.
