In New Hampshire this week, Sen. Robert J. Dole (R-Kan.) began running a new 30-second television commercial, "Can't Spend," in which he outlines his support for measures to reduce the federal deficit, including the line-item veto, a balanced-budget amendment to the Constitution and a budget freeze.

But insiders question how much the campaign can keep spending for the services of Don Ringe, the media consultant who made the spot. A campaign source said Ringe, who signed on last November with a contract said to be worth $40,000 a month, was to have received a $70,000 balloon payment this week to keep him on until early April.

But campaign officials reached Ringe last weekend in Nassau, the Bahamas, where he was taking what he described as a "two-day working vacation," to inform him of cash-flow problems. On Monday Ringe renegotiated his contract to end on March 8.

"We have to determine the number of spots to be produced, based on the resources available, for media for 'Super Tuesday,' " Ringe said. "I don't think any of us know where we stand. We won't know until we see how we do in Iowa and New Hampshire. If Dole gets the nomination, I'm sure I'd be asked to come back."
