Labus cannot win (bar the election hijacking, which is not at all excluded). Djindjich has some very powerful friends in the underworld who would like to keep their privileges intact. Serbia is sliding towards a similar situation that Russia found herself in under Yeltsin. That is if Labus wins. If Dr. K. wins -- which is almost certain -- there might still be hope for Serbia to become a normal country.
BTW, Labus' election HQ is the ex-HQ of the Beogradska Banka, which he and the Governor of the National Bank 'liquidated' this past February and left some 10,000 people jobless. Now they're using a couple of hundred square metres in that building for their election campaign. They have a 6 million dollar budget. Now we know where at least a part of the foreign aid received so far has gone.
Dr. K. has done more than anyone to keep Yugoslavia together. He's still committed to the work and will be committed to it even after he becomes President of Serbia.
