Four polling places have been set up at Hogsmeade (the largest), Portree, Montrose, and Banchory (the smallest). Voters can cast their ballot at any polling station but the poll books are connected so that signing in at one station marks the voter as voted at the other stations.
Each voter receives a ballot with the following question:
Shall the Minister for Magic appoint a Minister for Scottish Affairs as a Member of the Wizengamot and form a department for Scottish Affairs?
The options are to vote AYE or NAY.
Just as the voting booths are screened from sight and scrying, the comments to this post are screened.
