Following the RP_Newsletter account is great, because 140 characters of the Ron Paul Newsletters is about as much as I can stand in one gulp. The Twitter account publishes actual quotes from the presidential candidate's publications.
Here's one: "I've urged everyone in my family to know how to use a gun in self defense. For the animals are coming." And another: "If you have ever been robbed by a black teenaged male, you know how unbelievably fleet of foot they can be." Wait, one more: "The criminals who terrorize our cities -in riots & on every non-riot day- are not exclusively young black males, but they largely are." Okay okay wait, just one more! "At least 39 white women have been stuck with used hypodermic needles -perhaps infected with AIDS- by gangs of black girls."
