As Israelis head to the polls on Tuesday with the election outcome very much in doubt, the political fate of Prime Minister Benjamin Netanyahu could ultimately hinge on the appeal of marijuana legalization among young Israeli voters.

In Israel’s complex parliamentary system, polling is notoriously unreliable, especially because it’s banned in the days leading up to the vote, and thus surveys cannot pick up late movement. But the most recent polls find Netanyahu’s Likud party either tied with the center-left Blue and White, or within two seats. More important than who holds the most seats, however, is which party is able to cobble together a coalition of other parties to garner a 61-seat majority in the Knesset, which is the Israeli parliament.
