RFK & Joe McCarthy
The vast majority of good, decent, hard-working Americans have long reviled Communism, as exemplified in the former USSR. None detested Communism/"economic tyranny" and none more than John and Robert Kennedy.
Robert, along with Roy Cohn, were "Tailgunner Joe" McCarthy's right-hand men and JFK was one of the most ardent anti-Communist Presidents America ever had.
Being anti-Communist is righteous, as Communism amounts to "economic tyranny" and opposition to economic freedom, but being anti-Russian is just ethnic bigotry, pure and simple. That's something too many of today's Democrats seem to feel far too comfortable trafficking in.
