Actually, an immediate update. The above results are not exit polls, but rather come from CeSID - an independent group doing its own tallying from actual returns. They've finished their (unofficial) count. The Electoral Commission, which will provide the official count, will report later (their counting is independent, but uses the same raw data).
The full CeSID results (which, mainly, differ in that 7 seats are allocated to minority parties, which, apparently, are not subject to the same 5% threshold) are (in the order on the ballot, w/ the head of the list ):
Turnout 60.4% (of which 97.7% are valid ballots - nearly 4 mln. of them)
Democratic Party (Boris Tadic) 22.9% (65 seats)
G17+ (Mladan Dinkic) 6.8% (19 seats)
Liberal Democratic Party (+ a bunch of coalition partners) (Cedomir Jovanovic) 5.3% (15 seats)
Serbian Radical Party (Vojislav Seselj) 28.7% (81 seats)
Democratic Party of Serbia (Vojislav Kostunica) 16.7% (47 seats)
PSS (?) (Bogoljub Karic) 1.8% (no seats
Serbian Renewal (movement?) (Vuk Draskovic) 3.1% (no seats)
Union of Vojvodina Hungarians (Jozef Kasa) 1.3% (3 seats - minority party)
Party of Retirees of Serbia/SDP (J. Krkobabic/N.Covic) 3.2% (no seats)
Sandzak List Coalition (Dr. Sulejman Ugljanin) 0.8% (2 seats - minority party)
Sociallist Party of Serbia (no leader?) 5.9% (16 seats)
Branko Pavlovic list 0.4% (no seats)
Coalition of Vojvodina Parties (Igor Kurjacky) 0.2% (no seats)
Union of Serbia's Roma (Dr. Rajko Duric) 0.4% (1 seat - minority party)
Reform Party (Dr. Aleksandar Visnjic) 0.0% (just over 1500 votes - no seats
)
Democratic Unity of Serbia (Dr. Obren Joksimovic) 0.1% (no seats)
Coalition of Albanians of Presev Valley 0.3% (no seats)
Social Democracy (Nenad Vukasovic) 0.1% (no seats)
Hungarian Speach Coalition (Andras Agoston/Dr. Pal Sandor) 0.3%
Roma Party (Sajn Srdan) 0.5% (1 seat - minority party)
Once again, note 3 seats going to Vojvodina Hungarians, 2 seats going to Sanzak Muslims and 1 seat each going to two different Roma parties.
