Of course Skerry doesn't want the book in print again. He's fortunate that few copies were sold, and virtually all pitched in the trash years ago. That book was designed to get him name recognition for Massachusetts elections in the early 1970s. Once he was securely in office, he focused on his ultimate goal, which requires acceptance among a national audience.
Why do you think he's never standing alongside Kennedy, Feinstein, Boxer & Schumer at the gun-grabber press conferences? He votes exactly in step with the commies, but never proposes legislation or speaks out in favor of them.
He knows darn well that if everybody saw that book, he's win electoral votes in CA, MA, MD, and DC, and probably nowhere else. (edit:I forgot the People's republic of Hawaii, he's a shoe-in there too, even if he was found cavorting naked in Saigon with Jane Fonda they'd vote for him)
