Here's the back story.... As King William the Conqueror, all my sons have proved unworthy for the throne, particularly my firstborn whom I ended up executing after he dared plot against me. Fortuitously, my youngest daughter turned out to be a genius, and, under my tutelage, acquired many other desirable qualities in a leader. She is clearly most worthy to continue the de Normandie dynasty. So, upon changing to elective succession, I found a worthy Norman husband for my daughter (coincidentally also named William), who agreed to a matrilineal marriage. I granted him the Duchy of Normandy and nominated him my heir, allowing him to rule "with" my daughter.
Now, I hold the Duchy of York, my heir holds the Duchy of Normandy, and the Duchy of Northumberland is held by the sole surviving Saxon noble from my conquest. Oddly, my heir doesn't vote (either for himself or anyone else). Is that because the Duchy of Normandy is a de jure duchy of France, not England? If I create and hand out more duchies in the future, it would be nice to have 2 secure votes for my heir, or does the nominee not get to vote?
