你的未来枢机是意大利文化将很有用。如果这个孩子不是意大利文化，参见通过教育转变文化。考虑让你自己转变为意大利文化。You can always search for Italian characters by right-clicking any Italian character, selecting "go to character relations", and limiting the search to "my culture" [sic]. Alternatively, try to convert Rome to your culture, so it is your culture (rather than Italian) that gets the cardinal appointment score boost.
When he reaches the age of majority at 16, order him to take his vows. Becoming a will remove him from any succession lists and give him a monthly piety boost (until he loses the trait upon becoming a bishop).
If he is the son of a ruler and has high martial skill, try to get him a bishopric quickly, or he may try to join a holy order (costing you piety if you refuse).
If a Crusade is called, have him lead an army in the target kingdom to get the trait.
The secular power of the bishop is a major factor in cardinal selection. Most candidates are mere baron-level bishops; yours can have an edge. Furthermore, higher-rank clergy have more chances to gain monthly piety from church buildings. Their increased demesne limit lets them hold more churches, and they can have more vassals with churches, both baron-level and count-level.
You can create county-level bishoprics out of Holy Warred lands, or by revoking a county and granting it to a local bishop. You can then grant a duchy to the prince-bishop, making him a prince-archbishop. The technique is largely the same as for creating vassal republics. Theocracies cannot be granted kingdoms or create kingdoms, but it is possible to set up a theocratic kingdom by pressing a bishop's claim on a kingdom.
Keep in mind that you cannot create more theocratic counties if more than 10% of your realm is controlled by theocracies. You must choose between having a large number of count-level direct vassals (preferably in safe, uncreated duchies) or a small number of higher-rank vassals.
If you have lots of money, construct piety-generating buildings in the temples belonging to your cardinals and their direct vassals. You can also build new temple holdings for them, even in counties controlled by feudal rulers—you are not obligated to transfer the temple holding to the local count.
If you have Papal Investiture, nominate the member for the priesthood by asking the Pope himself. If he consents to the nomination then your designated family member will succeed to the next available bishopric within your realm.
Assassinate bishops in your realm to speed up investiture.
Holy warred counties can be converted to theocracies and given to your chosen person at the same time, bypassing the need for investiture (once).
To acquire the "In Rome" modifier, appoint your potential Cardinal as your Court Chaplain and send him to Rome on a mission to improve religious relations.
If all else fails, contribute money to his campaign fund until he is the best candidate. You should contribute at least some money for the "Supported Cardinal Election" opinion boost, which gives +30 for 83 years.
If you're feeling particularly devious, you could assassinate a Cardinal (or Pope) to make room for a new cardinal.
As an alternative to creating cardinals in your own realm, it is possible to breed dynasty members in the Pope's court. The Pope is likely to make some of them bishops, and they will have an edge in cardinal/pope elections thanks to being in Rome and the correct culture.
