Yehuda Shlezinger is reporting now that they actually did not file the petition to have Lieberman disqualified. it turns out that head of UTJ Moshe Gafni nixed the plan. Gafni said that besides for the fact that they wont do anything about it, in 2021 MKs are allowed to say the worst anti-semitic things and nobody protests.

Besides for the fact that almost all the main politicians plus many reporters did protest Lieberman's words, that would precisely be the reason to file the complaint, not to not file. Regardless, I think Gafni was right. It makes them consistent with their regular policy. If they broke it now just because it was something said directed at them, how would they justify non-participation in such complaints in the future? Was this really more inflammatory than a candidate having said an entire city should be destroyed or support of terrorists?

Also, trying to disqualify Lieberman would end with some boomerang effect, likely giving Lieberman a boost. Ever since Lieberman said what he said, the boomerang effect has worked in the favor of the Haredi parties, with them gaining a lot of sympathy (that might turn into voters) and momentum.

I think blocking it was the right move by Gafni, both strategically and morally.
