There are no districts. Voters vote only for a party. Every party gets seats in the Knesset (Parliament) based on the percentage of the vote. (The Knesset has 120 members; if a party gets 10% of the vote, they get 12 seats.)
Before the election, each party publishes a list of their candidates, in numerical order. If a party wins ten seats, the first ten names on their list are elected.
In this instance, if a candidate is 24th on the Likud slate, they will not be elected unless Likud wins at least 20% of the vote.
