According to these people, Mrs. Bill Clinton and her allies spent $1.2 billion on her failed attempt at winning the presidency and Mr. Donald J. Trump and his supporters spent $600 million to garner the most electoral votes. This site says that the total number of votes cast in the election were 136,737,920. That means that in aggregate each vote cost $13.16. The individual cost would be slightly larger in view of the small amount spent by fringe candidates like Jill Stein and Gary Johnson, whose votes are included in the total.
Of course the individuals voting didn't receive the money. It was spent on television time, marketing, polls, signage, newspaper ads, etc. A quadrennial Keynesian fiscal stimulus that goes right to the bottom line of the media, since they don't need to pay the actors.
