Israeli Prime Minister Benjamin Netanyahu's prospects of retaining power are uncertain, after exit polls in the fourth national election in two years projected yet another stalemate.
Those parties have garnered 56 seats, according to the latest tally, and although backing from Raam could give them a sufficient number to form a government, they are fragmented and unlikely to be able to agree to work together.
His campaign focused on Israel's world-leading Covid-19 vaccination programme and his diplomatic success in normalising ties with some Arab countries.
That list includes former senior Likud member Gideon Saar, leader of the New Hope party that could win up to 10 seats, and who has ruled out joining a Netanyahu-led government.
Adding Likud's hawkish, religious allies, the pro-Netanyahu camp could control more than 50 seats.
"I will reach out to all elected officials who share our principles", he told supporters. "I think there will be a fifth election", said Amit Fischer, a 35-year-old PhD student voting for Netanyahu's strongest challenger, the centrist former television anchor Yair Lapid.
But amended forecasts indicated deadlock even with Mr Bennett's prospective backing, with a parliament divided equally between Mr Netanyahu's likely opponents and supporters.
Lapid has said he will not insist on being prime minister in an anti-Netanyahu coalition, if that helps unseat the premier.
Israel's longest-serving head of government, Netanyahu has managed to hold on to power through two years of inconclusive elections despite facing corruption allegations.
"I will do only what is good for the State of Israel", Mr Bennett said in a statement after the exit polls were released.
He has said he will not block the trial and looks forward to being exonerated, but critics suspect that if he forms a majority, he may seek parliamentary action to delay or end the process.
Bennett's Yamina party is, therefore, seen as a likely kingmaker.
Among its most controversial figures is Itamar Ben-Gvir, who has voiced admiration for Baruch Goldstein, the murderer of 29 Palestinian worshippers in Hebron in 1994.
A Netanyahu government with Mr Bennett and a clutch of other ultra-nationalists on board would result in one of the most right-wing governments in Israel's history. But that arrangement fell apart late past year with the lack of agreement on a budget, triggering the new round of elections.
Gantz is projected to win seven or eight seats in Tuesday's election, outperforming expectations but still a far fall from a year ago, when he was Netanyahu's main challenger.
But their agreement called for Netanyahu to hand power to the centrist Gantz after 18 months, something observers correctly predicted he would never do.
If Netanyahu can't reach a deal with Bennett and his opponents cannot unite, a fifth election is possible.
