I think it depends on if he somehow becomes president or not.
If he doesnt, maga will die with him. If he does, all the rules will have been changed and all he needs to do is appoint next in line. Even if people don't agree with the person he appoints, or the party tries to put someone else in their place, it will be too late.
The show world can get super competitive. If you end up with a prize animal, you can bring home a good amount of money from auction.
Not to mention, for some, its very personal due to the time invested. These kids can put sometimes up to a year, if not more, into raising an animal for a show. They feed them special and care for them in very serious ways, to make them look perfect for a show. It's like beauty pagent moms, but with kid brains.
