Ted Kennedy conspiring with the Soviets to block Reagan's re-election?

The wingnut blogosphere is having a field day over this one, probably rightly so. It sounds like a crazy idea and, in my view, borders on sedition:

In his book, which came out this week, Kengor focuses on a KGB letter written at the height of the Cold War that shows that Sen. Edward Kennedy (D-Mass.) offered to assist Soviet leaders in formulating a public relations strategy to counter President Reagan's foreign policy and to complicate his re-election efforts.

The letter, dated May 14, 1983, was sent from the head of the KGB to Yuri Andropov, who was then General Secretary of the Soviet Union's Communist Party.

In his letter, KGB head Viktor Chebrikov offered Andropov his interpretation of Kennedy's offer. Former U.S. Sen. John Tunney (D-Calif.) had traveled to Moscow on behalf of Kennedy to seek out a partnership with Andropov and other Soviet officials, Kengor claims in his book.

…Specifically, Kennedy proposed that Andropov make a direct appeal to the American people in a series of television interviews that would be organized in August and September of 1983, according to the letter.

"Tunney told his contacts that Kennedy was very troubled about the decline in U.S -Soviet relations under Reagan," Kengor said. "But Kennedy attributed this decline to Reagan, not to the Soviets. In one of the most striking parts of this letter, Kennedy is said to be very impressed with Andropov and other Soviet leaders."
