Decoding Israel's Electoral System: Bader-Offer and Surplus Votes
An in-depth look at Israel's electoral mechanics, exploring how the Bader-Offer method and surplus vote agreements determine Knesset seat allocation.
As Israel prepares for elections, the complex mechanism of surplus vote agreements and the Bader-Offer method takes center stage. Understanding how votes translate into Knesset seats is crucial for political analysis.
Historical Background
The current system replaced the "highest remainders" method in 1973 through an amendment led by MK Yohanan Bader (Gahal) and MK Avraham Ofer (HaMa'arach). The new system shifted favor toward larger parties to ensure stable governance and prevent extreme fragmentation, though critics argued it compromised proportionality.
How Mandates Are Allocated
After filtering out parties failing to cross the 3.25% electoral threshold, the remaining votes are divided by 120 to establish the electoral quotient. The remaining unallocated seats are then distributed using the D'Hondt method.
Surplus agreements allow allied parties to pool their votes, increasing their collective chances of securing additional seats during the D'Hondt calculation rounds.
