On the last day of campaigning, if this is their big message, they must be very worried about Haredi voters going to Ben Gvir in large numbers.

The statements coming out of at least a few UTJ MKs today has been to not vote for Ben Gvir because that would be sharing responsibility for someone who goes up, or encourages people to go up, to Har Habayit and are "chayevei kritut" - obligated in heavenly death of karet. Along with having a party that includes not religious people, including one who is Reform (I did not know that one of the members is Reform), so one is supporting that, and they will feel no obligation to look out for your interests.

The message is not wrong. Smotritch comes from a religious party, a "chardal" party. But Ben Gvir's party is not a religious party - it is a general right wing party. Smotritch and Ben Gvir joined a united party of the two factions together (3 if you count Noam of Avi Maoz) and it has been billed as a religiosu party, but Ben Gvir's faction was never actually considered religious, even though he himself is.

Interestingly, I am not sure voting for Ben Gvir is any more sharing responsibility than sitting with him in the same coalition and government. If he is so bad that one cannot vote for him as a chayevei kritot and supporting Reform, then one should not join the government with him and support him as minister. UTJ is putting themselves either in a serious dilemma or in a hypocritical situation. 

And the issue that was raised when Degel and Aguda almost broke up that Degel accused Aguda of sinking the ship because of the Belz educationalal stance, and Aguda accused back that Degel formed a party to join WZO and sit with the Reform (that Degel was able to vehemently reject because officially it is not Degel even though they were behind the entire thing and Degel people pushed it) will surely come back accusing Ben Gvir of sitting with Reform and his voters supporting Reform.

All this shows that UTJ is very scared of the trending of Itamar Ben Gvir and how it will affect them.

And interestignly, Benjamin Netanyahu appeared the other day with Aryeh Deri at an event, and since has also gone to Bnei Braq to try to campaign for UTJ and tell haredi voters to vote and not stay home, along with sending out "robocalls" to the Haredi kosher phones... yet when he defended himself from Ben Gvir's anger about Bibi refusing to appear on stage with him, Bibi said that during a campaign it is normal to not appear with members of another party. So he couldnt appear with Ben Gvir but he could appear with Deri and make calls for Gafni...
