In 2013, 1,000 American citizens were polled and the numbers showed that the majority of those polled wanted mandatory drug tests for members of the US Congress.
The call is a move against potential hypocrisy in which some congress people actually use the drugs they are working to keep illegal. A few years ago, a cargo ship loaded with 90 pounds of cocaine was stopped by the coast guard. It turned out the boat was owned by Senator Mitch McConnell's father-in-law (also one of his largest financiers). Oddly, no charges were pressed.
Entering the US Congress does give an individual a semblance of power, but it doesn't wash them clean of their dirty human urges.
Where do you stand on drugs in Congress.
