Deletion of Swiss sovereign money referendum, 2018

Comment: as well as being somewhat promotional, there's already the mentioned overall year article. The other referenda of the year don't have articles - this certainly is not special enough to require it. The summary in the article is already present, and somewhat more neutral, so there doesn't seem a great deal of benefit to be bought. Many of the current sources are either  or non-neutral
