MPR News has an article about how much Michele Bachman paid to retain her seat in the United States House of Representatives. According to the article the cost per vote of winning was $65.19. Her opponent, Jim Graves, spent $8.70 per vote. Of course, he lost by 4,297 votes. Since he could have lost for a lot less than that, I suppose Mr. Graves overspent on his votes.
Although I do not think it was the point of the article, the story made me wonder how much Mr. Graves would have needed to spend to get 2,149 people who voted for Congressperson Bachman to switch to Mr. Graves. Obviously, it was more than $8.70. But would Mr. Graves have needed to match the $65.19? Or Would a lesser amount have worked? Would it cost more to get those voters to switch? Given the disparity between the expenditures, one might also wonder whether Bachman campaign was not spending money in an efficient manner. Was such a large amount per voter necessary after Congressperson Bachman spent most of the summer claiming to be an Iowan?
