The Arab list tipped the balance for Lapid and pushed Bibi out.
https://www.juancole.com/2021/06/pal...democracy.htmlAfter the last election, neither the far right wing Binyamin Netanyahu nor his main rival, centrist Yair Lapid, could put together a 61-seat majority with the Jewish parties. Abbas made it clear that his United Arab List was available for coalition-building. Natanyahu toyed with the idea, but his coalition includes far right Jewish religious parties who vowed never to form a government with the help of Muslim Palestinian-Israelis.
So then the centrist and thriller writer Lapid was able to pick up the United Arab List as one of eight diverse parties in his coalition, with those four seats getting him to 61. He wooed the right wing extremist Naftali Bennett and his small Yamina Party with an offer to rotate the prime ministership, letting Bennett go first, for two years.
