If a candidate is far behind in the polls then he just wants the day to end and the final count be done. The likely to lose candidate will be thinking about how to close down the office and file final reports. There will be little help usually in accomplishing it. Depression and feelings of rejection rule the day. Life sucks.
If a candidate is sure to win on election day he goes through the motions of staying busy and being happy. If it is a primary election there is only one thing in mind. The general election campaign. And it starts all over.
