Yeah they do, and also everyone is assigned a particular place. You get your assignment in the mail. The vote is inside an outside envelope (two envelopes total). The outside envelope has your identifying information. If you vote at the wrong place, your vote is discarded. So, you don’t drop your vote into a box and no one knows where it came from. You have to clear all the checks before your vote is counted, and only then is it anonymous ... :-) ...
I also learned that Israeli citizens don’t vote directly for their leaders? So, do they vote for a political party/group?
