I don't know why these questions haven't been asked by the media.  They need to be asked now before Hillary steps aside.  There is no doubt they are legitimate questions and will be raised before November.  After all, any Federal Employee who admits drug use is subject to drug testing.  Senator Obama please tell us now:

1.  When was the last time you used drugs?

2.  Did you ever sell drugs?

3.  Did you ever give someone drugs?

You have been candid about your drug use and by doing so, you have opened the door with regard to this topic.

Everyday people applying for jobs with the Federal Government are asked about their past drug use.  For example, according to the Washington Post:

The CIA, for example, requires that applicants have not used illegal drugs within the past 12 months, although "illegal drug use prior to 12 months ago is carefully evaluated during the medical and security processing," according to an agency advisory.

Even the DEA leaves open the possibility of hiring employees who admit to "youthful and experimental use of marijuana."

"Such applicants may be considered for employment if there is no evidence of regular, confirmed usage and the full-field background investigation and result of the other steps in the process are otherwise favorable," according to the DEA's Web site.

At the FBI,  new rules allow the bureau to consider "all relevant facts, including the frequency of use," in deciding whether someone's drug history should bar a candidate from becoming an FBI employee.

If the average citizen is subject to these questions, certainly they should apply to those seeking the Office of Commander and Chief.
