Democratic Presidential candidate Sen Alan Cranston (D-Calif.) brought his "Peace and Jobs" campaign to the Law School yesterday, attacking President Reagan's defense posture as "simplistic, superficial, and paranoid."

Cranston's Harvard speech came during a day of stumping in Boston, which included stops at three other campuses, a speech before a local disarmament group, and private meetings with supporters.

Throughout the tour, the liberal senator, considered to be third behind former Vice President Walter F. Mondale and Sen. John Glenn (D-Ohio) in an eight-man field, echoed the twin themes of his campaign; stopping the arms race and eliminating unemployment.

This included outlining a proposal to include French and British missiles in intermediate-range nuclear negotiations and to halt the deployment of Pershing II and Cruise missiles in Europe.

In an evening interview, Cranston insisted his stance on Euromissiles would not encourage Soviet adventurism.

"We have never had a war with them," he said, "except that now tensions are at an all-time high."

Why Not the Best?

Cranston has stressed throughout the campaign that he is the best candidate to reduce the threat of nuclear war because he has made stopping the arms race his number one priority.

The distinction between him and front-runner Mondale, he said, "is mainly a matter of putting my priority on the arms race."

"[Former President] Jimmy Carter didn't focus his efforts and got lost in the shuffle," he said. "Walter Mondale sold the Europeans on the Pershing and Cruise missiles [when he was Vice President in 1979]."

Cranston likes to talk about a meeting with the late scientist Albert Einstein at the close of World War II, when the Californian said he first began to speak out against the nuclear arms race. But, he added, "I didn't get any attention until I became a Presidential candidate."

Cranston said he is not afraid that his out spokenness on the nuclear issue will overshadow the rest of his platform. "I say enough about other issues, but I think that if we blow ourselves up, other issues won't matter."

And while he accepts being termed a "liberal," he said. "The issues I'm running on are not liberal issues, but mainstream issues."

Before an audience of about 125 at the halffilled Ames Courtroom. Cranston detailed his program to revive the economy Restoring taxes reduced as a result of the Kemp Roth tax bill, eliminating the MX missile system and other defense projects, and increasing employment would "lead us towards a balanced budget," he said.

Cranston predicted that the deficit would be reduced by $30 billion for every million people put back to work.
