Important Note: Originally I posted the poll that was broadcast which turned out to be the wrong poll. Their website provided the correct results.
Panels conducted a poll of 575 people for Walla that was broadcast on July 8 2018. They also conducted three additional scenario polls.

The results don’t make sense when you compare them. I think that the population samples aren’t varied enough.
I think much of the population simply doesn’t know who they are voting for until they are literally in the voting booth. Watching polls and results for 12 years now I think there are 7 surprise seats worth of these voters who often end up breaking as a block. They broke for likud last time, they broke for lapid two times ago and they broke for pensioners in 2005 for example. These voters are the reason these polls are always off…instead of just answering that they are still undecided they tell the pollsters they are voting for some random party.
