As the beginning of the American Presidental Season barely rounds the corner, everyone is jumping to the shocking news that the year's 'war chest' is going to be in the millions, and I have a question.

When the season is over, what of the money?
Everyone donates to their candidates, and at the end of the year, what happens to the money?
Where does it go?
Can it be put to better use? Giving it to charities, decreasing the national deficit, scholarships, something?
