Obviously this caused an outcry.

Putting aside the latent racism (or maybe not so latent), Sukenik is just wrong. The Likud representatives are [mostly, if not all] highly intelligent. They hold degrees and doctorates. People Like Benjamin Netanyahu, Yuval Steinitz, Gilad Erdan, Yisrael Katz, Avi Dichter, Ofir Akunis, among others. They are highly educated, along with having spent many years in service of the country. Even the MKs who are loudmouths, such as Dudi Amsalem, Shlomo Karhi an Miri Regev, among others, are highly educated and intelligent.

And one might say the Yesh Atid representatives are actually less educated than the Likud representatives. I am not as familiar with them as I am with the Likud reps, but just starting from the top, Yair Lapid did not even complete his matriculation exams. I looked up some random MKs and they all seem to hold degrees and even masters degrees, so it is generally wrong to say this about them as well, but the head of the party is not educated and he is the one who sets the tone and agenda for Yesh Atid. In his case one might say education is less important as he is accomplished and has shown himself to be a leader. So I would not say either are less intelligent or educated than the other.

Talking like this helps nobody. Just the opposite - it only hurts the people he is trying to help. But it also shows his own ignorance and bias. 

And on the other end of it, we have MK Miri Regev today trying to scare the public saying that if Yair Lapid becomes Prime Minister he will remove the words "nefesh yeshudi homiya" (A Jewish soul yearns) from Hatikva, the national anthem, as he will have to as a result of partnering with Raam.

Let's raise the level of discussion all around.
