You mean what attracts 6% of the (Vojvodina) voters to him? I don't know. 6% is an acceptable percentage of absolute lunatics... I suppose.
BTW, this has nothing to do with the DSS. The DSS MPs didn't vote for it. The DSS has drafted a proposal for the new Constitution of Serbia (which is open to discussion and amendments). However, my sources tell me that Mr. President is hardly in favour of the draft proposed by his own party, primarily because of Vojvodina and Rashka (so-called "Sandzak").
What I find stupid is the fact that the DSS has proposed this new Constitution which envisions Serbia as a 6-region republic ( [autonomous] Vojvodina, Kosmet, Belgrade, Nish, Uzhitse and Kraguyevats) but at the same time they do not appear to be in favour of giving autonomy to Vojvodina.
The other thing, my opinion is that Banat, Bachka and Srem should be separate regions (in other words - abolish the Province of Vojvodina) of Serbia. Other parts should have no autonomy because Serbia was never a republic or a kingdom made up of regions or provinces. Never in its entire history. Vojvodina, on the other hand, has always been a union of regions. The region of Baranya also used to belong to Vojvodina but that bastard Tito annexed it to Croatia.
My solution would be to decentralize the state and give more power to the municipalities (opsthinas) without creating some new regions, provinces, etc.
As for DSS using a foreign name for Rashka, I noticed that DSS sometimes tries to be too politically correct. Even DSS itself is a mini-DOS within -- fractured into various factions and special interest groups. Disunity has been Serb enemy number one from day one. They can never agree on a common goal and exaggerate their differences to extremes.
Vojvodina is correct. Srem, Banat and Batchka should be considered instead of the so-called Vojvodina. BTW, Baranya was given to Croatia by a "Serb from Montenegro" as he used to refer to himself at the end of his miserable life -- that bastard Milovan Djilas, not that "bastard [Josip Broz] Tito" as Vojvodina claims. That "gift" on Serbia's behalf was in return for Croatia's "generous" agreement to grant Bosnia a tiny sliver of land as access to the Adriatic sea by Vladimir Bakaric, Croatia's communist party boss and Tito's confidant.
BTW, Voyvodina means "Dutchy" (from voyvoda, or voyevoda, which is duke in Serbian). Since Serbs do not have dukes, obviously the name refers to the Austro-Hungarian dutchy, not a Serbian possession. Srem, Banat and Batchka (SBB) is therefore a more appropriate name for the region, which no longer belongs to foreign dukes. However, historically, Vojvodina was settled by Serbs pretty much in the same fashion as Kosovo was settled by Shiptars. The fact that Vojvodina voted for union with Serbia in 1918 is about as legitimate as Kosovo voting for union with Albania. For all practical purposes, the Serbs stole that region by overpopulating it.
