I think a little clarification is in order:

George Rekers is a rentboy-hiring anti-gay crusader, who was hired by various state governments to provide expert witness that gay adoption is bad.

George W Bush is an ex-president who used to do a lot of drinking and partying. There is a suspicion that he may have used cocaine on occasion.

Al Franken is a current senator who had a former career as a comedian. There are rumors that he may have used cocaine on occasion.

Barack Obama is the current president: he has stated that he used cocaine on occasion in his youth.

Carry on.
