Netanyahu’s 3 Major Hurdles in Israel’s Election

Israelis go to the polls tomorrow for an election that could decide the political fate of Prime Minister Benjamin Netanyahu, whose appearance before a joint meeting of Congress early this month sparked anger from the Obama White House and controversy on Capitol Hill.

Foreign elections are typically not something most Americans follow particularly closely, but this one’s different. The fresh controversy over Netanyahu combined with the ongoing negotiations over Iran’s nuclear program, which Netanyahu has denounced, has sparked more interest than usual.

Here are three things you need to understand when tomorrow’s election results roll in.

Israel’s Government Is a Parliamentary System

Strictly speaking, Israeli voters aren’t electing a Prime Minister. They are electing a new Parliament. Unlike the de facto two-party system in the U.S., there are numerous thriving political parties in Israel, none of which is expected to garner anything close to enough seats in Parliament to constitute a majority.

As a result, when the tallies come in Tuesday night, it may not be immediately obvious who the next Prime Minister will be. Netanyahu’s Likud Party, according to the most recent polls, is expected to win fewer seats than the left-leaning Zionist Union Party (itself the product of a merger between two other parties.) However, both are predicted to win between 20 and 30 seats, leaving them far short of the 61-seat majority needed to form a government.

That means when the polls close, the dealmaking begins. Likud and Zionist Union begin bargaining with small- and medium-sized parties in an effort to build a coalition that will boost one side to the necessary 61 seats. It’s far from clear who will have the easier time of it, and it can be a messy process. Coalitions are formed on the basis of bargains – a top cabinet post for a leader who can bring key lawmakers with him, or a promise to pay particular attention to issues important to another bloc in exchange for their continued support.

Netanyahu currently leads a coalition government, and the reason he has called this election, only 26-months into what could be a four-year term, is that he has found his coalition unworkable.

Israelis Have More on Their Minds than Iran

In the U.S., it will be tempting to view the results on Tuesday as either an endorsement or a repudiation of Netanyahu’s position on Iran. In fact, Netanyahu himself has done his best to make the election about foreign policy in general, and the threat of a nuclear Iran in particular.
