That one or more backroom deals are made to settle the delegate votes. It normally begins, as stated, with no candidate having the votes required to win the nomination outright. In that case, the dealing begins to put together the votes. Sometimes, a VP or cabinet slot is the carrot, but most often it is just space in the convention agenda. This is most often accepted to cement someones future prospects. My guess is one or more of the top four candidates will be getting deals like this is sweeten the pill of going quietly into party unity.
