Nixon thought Oppenheimer was innocent and he has never been proven wrong on any of his hunches. Kitty was most definitely a commie.
When you have Steve Nelson over to tea, see "Venona Papers" and others, you have a commie plot. Steve was the commissar of the Abe Linclon Brigade and later head of the commie underground on the left coast, see the Yale University series on the American Commie Party.
While we are at it I campained for Nixon and even then I thought he had his head up his butt, see EPA.
