Israeli polls do not take the electoral threshold (currently 3.25%) into account in a uniform fashion. Some polls report the number of seats each party would win purely according to the percentages, as though there were no threshold; others eliminate parties that poll below the threshold and distribute the 120 available Knesset seats only among those who pass it. As a result, parties that poll at or near the threshold can show inconsistent results, bouncing between 0 and the minimum 3 or 4 seats.
Polls may not add up to 120 seats due to rounding or omitted parties that drop out or do not poll consistently.
