The poll found that, across the political spectrum, large percentages of Israelis will not vote for the same parties that they voted for in previous elections.
This is particularly pronounced among left-wing voters, the poll claims.
Only 23% of Yesh Atid-Telem voters will vote for Yesh Atid-Telem again, 4% of Labor voters will vote for the party again and 53% of Meretz voters will vote for the party again, according to the poll.
Gideon Sa'ar's new party will pull votes from a variety of parties according to the Channel 20 poll. Some 10% of Likud voters will vote for Sa'ar's New Hope Party, with 18% of Blue and White voters and 14% of Yamina voters planning to vote for Sa'ar's new party.
A recent poll taken Thursday for The Jerusalem Post's Hebrew sister newspaper Maariv found that Sa'ar would be able to form a government with Yamina, Yesh Atid, Yisrael Beytenu and Blue and White, leaving Prime Minister Benjamin Netanyahu's Likud, Shas, United Torah Judaism, Meretz and the Joint List in the opposition.
The poll predicted 21 seats for Sa'ar's New Hope Party, just five seats less than Likud.
The Panels Politics poll found that Netanyahu's Likud is the leading party ahead of the March elections with 25 mandates, trailed closely by Sa'ar's New Hope at 22.
Yesh Atid, Yamina and the two haredi (ultra-Orthodox) parties combined are all tied next at 15 mandates, according to the poll (Shas with eight and UTJ with seven), followed by the Joint List at 11 and Avigdor Liberman's Yisrael Beytenu at seven seats.
Closing out the poll were Meretz, which rose slightly to six mandates, while Benny Gantz's once mighty Blue and White Party has fallen to four mandates and is nearing the electoral threshold.
