A reader sends in an anti-Pryor mailer received from Americans for Prosperity. It seems like $71,000 spent on monkeys under the influence of cocaine* has been the single dominant issue in the Senate race in Arkansas, so it’s perfectly reasonable that AFP would choose this particular imagery to highlight in a mailer.
*p.s. This is a four-year-old, misleading gambit. Republicans love to point to scientific research that sounds silly out of context. This was a grant awarded by the National Institutes of Health via a competitive process to researchers at Wake Forest University to learn more about treating drug addiction in humans.
