Who is most suited to be Prime Minister?
35% Netanyahu, 11% Bennett, 11% Liberman, 9% Ashkenazi, 9% Herzog, 19% none.
Knesset Jeremy Analysis: If Ashkenazi enters politics it has a one to two seat change on the blocs. Regardless the Anti-Netanyahu alliance of Yesh Atid-Zionist Union-Meretz-Joint List fails to get close to forming a bloc large enough to block Netanyahu in a stage 2 situation by the President residence.
In the unlikely scenario of a mega-Lapid-Kahlon-Ashkenazi-party, the party would still fall short of a coalition even after signing coalition agreements with Zionist Union, Meretz and Yisrael Beitenu. The likelihood of the 50-seat-bloc of Likud and the religious parties joining a coalition with Lapid would be extremely low and the Arab parties are against joining any Zionist government.
