In the call to Jewish New Yorkers, Mr. Allen said, the caller asks: ''Did you know that before Mrs. Clinton started her run for our U.S. Senate seat, she supported a Palestinian state and didn't support moving the U.S. Embassy to Jerusalem?'' According to Mr. Allen, the caller goes on to say that Mrs. Clinton took money from an organization that ''openly brags about its support of Hamas and Yasir Arafat, a group that our own State Department called a terrorist organization because of its attacks on Israeli civilians.''

In June 1999, Mrs. Clinton broke with her husband's administration and said in a letter that she wanted the United States Embassy moved as soon as possible to Jerusalem from Tel Aviv.

In the Republican committee's calls to non-Jewish New Yorkers, callers say that Mrs. Clinton accepted money from an organization that ''openly brags about its support for a Mideast terrorism group -- the same kind of terrorism that killed our sailors on the U.S.S. Cole.''

Officials of the American Muslim Alliance acknowledge that some members have hard-line views against Israel, but they say the group is essentially mainstream and advocates peaceful solutions to the Mideast conflict. Its support has long been actively courted by politicians of both major parties -- notably Gov. George W. Bush of Texas, who recently accepted its endorsement for president.

A co-founder and former president of the American Muslim Alliance, Farooq Ansari, expressed distress last night over the telephone campaign. ''We are just as good citizens as anyone is,'' Mr. Ansari said. ''Associating Muslims in this country with terrorists is nothing less than McCarthyism. It is totally false, inaccurate and should totally be stopped.''

Mr. Allen said the Cole reference was not included in the call to Jewish voters only because each script had to be limited in length. He said he did not know the process by which New Yorkers were identified as Jews and non-Jews. He also said he was unable to provide a written text of either script last night.

Mr. Powers, the state Republican chairman, is a former marine known for advocating particularly tough campaign tactics, a trait that has been on particular display in this contest to succeed Senator Daniel Patrick Moynihan, who is retiring. For example, Mr. Powers wrote a fund-raising letter that described Mrs. Clinton as an ''ambitious, ruthless, scheming, calculating, manipulating woman.''
