One sign I saw looks fine, mentioning Achdut in Bet Shemesh under Abutbol (because he signed support with Agudat Israel and expects to sign with other parties, so he is calling that Achdut). The other sign being plastered around is less understandable, at least to me.

The slogan on these signs say "Aryeh needs a strong Moshe, Moshe Abutbol for Mayor of Bet Shemesh".

Why? Why does Aryeh need a strong Moshe? How does a strong Moshe as Mayor of Bet Shemesh help Aryeh Deri doing anything specific in the government? Feel free to enlighten me.

I do get that it is a play on words using a similar campaign theme to the last Shas campaign in the national elections, saying Bibi Needs a strong Aryeh", but at least that made sense - Bibi needed a strong turnout of support for Shas to form a stable coalition. That makes sense. I guess they are banking on that theme in people's minds, but I dont get a strong Moshe helps Deri or how a weak Moshe hurts Deri. Of course Deri wants him to win, but how does this hurt or help Deri?
