Hello. I am writing a research paper on municipal elections in Saint Petersburg. The recent elections of 2019, according to observers, were held with a large number of violations. In my work, I try to check this. But I have some questions. If I understand correctly, the elections are held using the “Multiple non-transferable vote”/Block Vote system. In other words, the voter can choose up to five candidates from the entire list, and the winners are those who received the highest number of votes in all precincts. Are there any countries with such a voting system, and open data about elections? For example, in Russia, it is possible to view data on each specific polling station where elections were held, for example, how many votes were cast for candidates, how many ballots were issued, etc. Could you recommend literature specifically about this voting system?
