As much as Trump would hate losing, Hillary is no different in that regard- many reports from a variety of news outlets had quotes from staffers, saying that she was inconsolable and that she disappeared on election might because of that.
Obviously on a much smaller level, but I worked with a couple of guys who couldn't stand being the #2 salesperson. One went so far as to create false receipts and take credit for sales that never happened, the other was so suspicious that he looked in the other guy's commission books and made random calls to the people whose names & phone numbers were on the receipts. Several said they had never been in the store and some had never heard of us, so he gave that info to his uncle, who owned the store and the guy who had been the #1 salesperson was immediately fired. This guy had won a trip to Mexico, too- had to pay for that, as well as the commissions he had been paid.
