ELI5: What do candidates for public office do with their leftover campaign money once election season is over?
gpt
In a competitive race, there is no money left over. None.  You may indeed go into debt in the final weeks and hope that friends will help you pay it off if you lose. (If you win, you will have many friends.)

In a non-competitive cycle, safe incumbents just roll their funds into the next year.  They'll use some of it to help candidates in competitive races in order to increase their own clout, and because it's good for the party.
