Americans Want Congress Members To Pee In Cups To Prove They're Not On Drugs
According to a new HuffPost/YouGov poll, 64 percent of Americans favor requiring welfare recipients to submit to random drug testing -- a measure pushed by Republican lawmakers in recent years -- while 18 percent oppose it. But an even stronger majority said they're in favor of random drug testing for members of Congress, by a 78 percent to 7 percent margin. Sixty-two percent said they "strongly" favor drug testing for congressional lawmakers, compared to only 51 percent who said the same of welfare recipients.
Especially since the time Rep Hank Johnson made a complete ass of himself when he, with a straight face expressed concerns about Guam tipping over into the Pacific because he thought we had too many military personnel there.
