Well... i personally think that is wrong for the media to mix the candidates personal life with their political carrers... what really matters is if he/she is a good politician when it is in its office, working... what one does outside the office is no one else business...
Its the same thing... if youre a hard working person, who pays all your taxes, no one should bother you because you smoke weed in the privacy of your home, since it does not interfere with your work.
