I'm currently king of Ireland and Scotland, and own about half of GB. One of my relatives got a claim on the Kingdom of England, so I managed to win that war and place my cousin on the throne of England. Having done this, now I'm trying to combine all three kingdoms.
I tried using elective monarchy, this works good in Ireland, because here only dukes can vote on a successor and I have only granted 1 person a duchy. However, in Scotland all the vassals can vote, including my counts. They keep electing random dudes and my question is how I can change this to the way my Irish elective works. I have selected minimal crown authority in both kingdoms.
