Israel’s recent elections were a reminder for many of the instability of the country’s electoral system. Since 1988, not a single government has lived out its entire four-year term. Under the Basic Law, the seats of the Knesset are divided in direct proportion to the percentage of the vote won by each party. There are no electoral districts; nor is there a system (as in Britain and France) to ensure a clear victor in every election. Binyamin Lashkar argues that a modest change might do much good:
We need to be very careful when changing the rules of the game. There are always unexpected results. Perhaps we could try [to amend the laws so that] elections are held for the first 100 seats in the Knesset, and the party with the most votes will then be awarded the remaining twenty. This is a significant addition for winning; under such a system, the public will no doubt prefer voting for likely winners. . . . Such a change will create an incentive for parties to unite and will encourage the formation of two large parties which can easily run the country. And the land would be at peace—at least for four years.
