As Israeli prime minister Benjamin Netanyahu travels to the United States to deliver a controversial address to the US Congress on Tuesday morning, he’ll leave behind him in Israel (if only for a couple of days) one of the toughest election campaigns of his career.

The Washington speech has sucked up much of the attention from Israel’s election campaign, both in the United States and in Israel itself. But that doesn’t guarantee that Netanyahu will win what would be a fourth term as prime minister and his third consecutive term since returning to power in 2009.

Netanyahu’s center-right Likud (הַלִּכּוּד‎), consistently since December, has been tied in most polls with the Zionist Union (המחנה הציוני‎), a merger between the center-left Labor Party (מפלגת העבודה הישראלית) and a bloc of moderates led by former justice minister Tzipi Livni, herself the former leader of the late Ariel Sharon’s essentially defunct Kadima (קדימה‎, ‘Forward’).

Though Israeli politics has become a dizzying array of fragmented, personalized parties, where political leaders denounce opponents one day only to join forces with the same opponents the next, Herzog and Livni both support a more progression economic agenda as well as the ‘two-state’ solution to the Israeli-Palestinian conflict.

The Zionist Union’s combined support means that Labor’s newest leader, Isaac Herzog, has emerged as the top alternative to Netanyahu to become Israel’s next prime minister. A soft-spoken attorney, Herzog isn’t known for his charisma or his bluster, and his chief quality might be that he’s regarded as the quintessential anti-Netanyahu, at least in style.

So how did Herzog (pictured above) get to this point? And what would a Herzog-led government look like?

Herzog wants to end Labor’s wilderness period

Though the Labor Party hasn’t won an Israeli election since 1999, it nevertheless has a storied legacy — it’s the party of Golda Meir, of Yitzhak Rabin, of Shimon Peres. Herzog himself is the son of Israel’s sixth president, Chaim Herzog, and he studied in New York in the 1970s when his father was serving as Israel’s ambassador to the United Nations. Herzog is Labor’s fourth permanent leader in a decade, and he hopes to lead Labor to its most successful election victory since the 1999 parliamentary elections under former prime minister Ehud Barak.
