I desperately need to get my dukes to vote for my blood relative, the King of Poland.
My current vassals are:
-Voting for the Duke of Pest
Duke of Pest and Nyitra
Duchess of Pest and Nyitra, my blood relative regularly married to the former (she was too old and her one kid died)
Duchess of Ungvar, the Duke of Pest's mom
-Voting for the Duke of Transylvania
Duke of Transylvania, friend of my heir
My kinsman, holds 3 ducal titles and ISN'T VOTING FOR HIMSELF
-Voting for my kinsman
Me
If I vote for another candidate of my bloodline, my kinsman will vote for them, but voting otherwise will cause him to vote for the Duke of Transylvania.
If I die, I lose my kingdom title, putting me as the regularly married Queen of Sicily, who's too old to have more kids.
So, in essence, how can I convince my vassals, all of which have 40 or greater opinion of me, to vote for my kinsman?
I have no other options. The most I could do is pass it off to the duchess of Pest and delay this for another generation.
