Differences crop up between Afghan President Karzai, Ministers

I just thought this was an interesting development in Afghanistan. I know for a fact that Fahim and Abdullah Abdullah are not Pushtoon but I don’t know about Younus Qanuni. Recently Rashid Dostum also announced his candidature for the presidency. Are all theser members of the Karzai Administration going against him because of ethnic issues or is it something else?
