Thirteen members of this working group.  Nationally, women outnumber men. Women's health concerns do not mirror those of men.  Since you can't have half (six and a half) of the group be women, there should be seven women in the group, some of whom are ethnic minorities, to fairly represent females of all ages and ethnicities.  Some of the six men also should be ethnic minorities to fairly represent males of all ages and ethnicities.  

Sen. McConnell gives us thirteen old white men.  

And I am not surprised.
