Politicians to be Drug Tested?

I have a simple question based on the fact that Alberto Gonzalez could hardly remember anything during his testimony: Shouldn't we demand that all persons who want to work in the public sector be tested for drug use on a mandatory and possibly regular basis? Of course it's demeaning and embarassing to be drug tested. These public officials need to be tested like the rest of us are especially because they have so many responsibilities. Maybe then this absurd testing of most job applicants in the private sector and even people who have pain problems (such as myself, yes I'm tested for drugs at a pain clinic simply because I have a major pain syndrome!) won't be required to be tested...eventually. I can understand that SOME job applicants need to be tested, such as those who want to perform transportation duties or skills that are physically dangerous, but this drug testing problem has really gotten out of hand. Let's put forth a bill, petition, whatever is necessary to embarrass politicians into negating drug testing requirements for those who testing doesn't make any sense. Excessive drug testing is a major way of infringing on our freedoms and liberties. Because of the recent glut of hypocrisy involving politicians lying about their homosexuality and other facts, I think we'll find that many public officials are also drug users (especially BECAUSE they claim so loudly that they are so dead-set against drug use).Let's drug test public officials. After they are humiliated long enough maybe then they will have enough empathy to curtail the overly excessive use of drug testing.
