In a somewhat surprising attack on Thursday, Jewish Home Chairman Naftali Bennett struck out at Kulanu Chairman Moshe Kahlon.
Speaking at a conference in Tel Aviv only days before elections, the Economy Minister accused the former Likud minister of tending toward the left within the political spectrum.
"I want to use this podium to turn to my brother Moshe Kahlon and say to him: stop moving leftward," Bennett said, while addressing the conference's crowd.
According to Bennett, "to be social does not also have to mean to be left-wing."
"To lower the cost of cheese, you don't need to hand over territories. To raise the minimum wage, like I did this week, you do not need to, G-d forbid, divide Jerusalem," he explained.
"I've been doing this for two years," Bennett stressed. "You can be both right-wing and socially-minded.
"I worried about the wages of contract workers, but I also prevented the building of Hamas tunnels. We lowered the price of food, and I stopped the release of terrorists."
"Kahlon, to be socially-minded, you do not need to be left-wing," Bennett charged.
"There is no reason that disappointed Likudniks should turn to Kahlon, who is left-wing. There is a social right-wing party and that is Jewish Home!" Bennett reminded the conference participants.
Jewish Home has spent most of its campaign trying to convince voters to choose it over Likud. The attack on the Kulanu party, which views itself as more centrist than right-wing, appears to be a new tactic.
