Portsmouth Herald RAN 2/15/96, Pg. A1 By Steve Haberman Herald Staff PORTSMOUTH - Kansas Sen. Bob Dole yesterday broke a promise he made during a recent visit to the Seacoast by running an attack ad against the man considered his closest rival in the New Hampshire Republican primary, political commentator Pat Buchanan. ``We're running positive ads in the last week,'' Dole told Celltech Biologics employee Dominic Calandara during a visit to the company's facility at the Pease International Tradeport on Feb. 8. Calandara had told Dole he was tired of the kind of negative advertising New Jersey publisher Steve Forbes had been airing in New Hampshire. Yesterday, however, the Dole campaign began airing an ad labeling Buchanan as ``too extreme'' and unable to beat President Clinton in the general election. In support of those claims, the Dole ad cited quotes Buchanan allegedly made, one dating back to 1983. The first, that ``women are simply not endowed by nature with the measure of single-minded ambition and the will to succeed,'' the Dole campaign attributed to one of Buchanan's syndicated columns that appeared in the St. Louis Globe-Democrat in November 1983. The second quote, allegedly from a Buchanan column that appeared in the Conservative Chronicle dated April 4, 1994, advocated the arming of South Korea, Japan and Taiwan with nuclear weapons. According to the Dole campaign, Buchanan wrote: ``If the British and French nuclear arsenals helped deter Moscow in the Cold War, why should not small nuclear arsenals in South Korea, Japan, Taiwan and Australia help deter the neighborhood bullies of East Asia who reside in Pyongyang and Beijing?'' Immediately after the Dole ad began airing, the senator's national campaign chairman, New Hampshire Gov. Steve Merrill, jumped on the bandwagon. ``He's getting kind of out there,'' Merrill said of Buchanan during an interview on WMUR-TV. Sources at the Buchanan campaign had no comment on the new Dole ad yesterday. They would only say that the political commentator planned to hold a press conference and shoot a new commercial at an as-yet-undetermined location today at 10:30 a.m. ``You'll have his answer then,'' a campaign spokesman said. Several calls placed to Dole's Concord office and his campaign headquarters in Washington were note returned. In contrast to Dole's decision to ``go negative'' during the last week before the New Hampshire primary, New Jersey publisher Steve Forbes, who finished fourth in the Iowa caucuses Monday and is seen as losing ground in recent New Hampshire polls, toned down his advertising. Many Iowa voters voiced displeasure with Forbes' negative advertising in that state. Forbes' most recent New Hampshire ads target the current Washington bureaucracy but no individual specifically. He also has begun to talk about other issues, such as his plan to establish medical savings accounts in order to save the Medicare system.
