Drug Test Before The Debate?

Its getting closer and closer to the election. Are you watching the debates and reading up on the two major party nominees?  Well if you aren't here is a little bit of information on whats happening with the Trump campaign. Trump is saying that he thinks Hillary Clinton is on drugs because of her performance during the last debate. He is calling her out on it and is saying that they should have a drug test before the next debate. I believe this ins't a bad idea after all. Does the president get drug tested? I never thought of that question before, I don't know about you but I have always just assumed they wouldn't be doing drugs. But he makes a good point. I think they should have a drug test and that if we as american citizens have to be drug tested for jobs than the president should have to drug tested also.
