Favorite son

The technique allows state leaders to negotiate with leading candidates in exchange for the delegation's support in subsequent ballots.

Conversely, a party leader who has chosen a candidate might become a favorite son to keep other candidates' campaigns out of the state,[2][1] or prevent a rival local politician from becoming a favorite son.

[1] The favorite son may hope to receive the vice-presidential nomination,[4] Cabinet post or other job, increase support for the favorite son's region or policies,[5] or just the publicity from being nominated at the convention.
