Israel may have a similar law but I don't speak Hebrew and I suspect any searches I do for this will get buried by the news of the leak, so I don't think I'll be successful in finding it.
Apparently, the parties voted themselves the right to that data when the election cycle starts (6 months or so before the actual elections, or something like that), under the promise that "they will keep it safe, and delete it afterwards, and only use it themselves". Needless to say, it has leaked out to marketers/private-investigators/bittorrent in basically every election cycle so far.
In this case the information included first name, last name, ID number, phone number, address and parents names
Voting record in this case means which elections you voted in, not who you voted for.
It is explicitly illegal to use these records to send advertisements, but who knows how well that works
