If you think today's campaign climate is full of vicious, inappropriate attacks, take a look at these actual Richard Nixon campaign buttons from 1972. Of course, the most shocking thing about these fellatio-implying tchotchkes is that Republicans 40 years ago were apparently less sexually repressed and more prone to humor than they are now. Then again, these are still child's play compared to the GOP's 1960 campaign buttons, "JFK Absolutely Can Lick Our Dick."
