"The price of one bona fide, registered American vote varies from place to place. But it is rarely more than a tank of gas."
A good book that descibes it is "Washington, D.C: A Novel (Narratives of Empire)." of Gore Vidal.
The headline is super misleading, the point of the article is that selling votes is more common than outright impersonation or other forms of voting fraud.
In Brazil they do it the honest way.
As voting is compulsory in Brazil, a lot of people vote on the person that appeared on the television, or the person that had pamphlets being distributed at the red lights, so spending money on campaign works, indirectly buying votes.

One could say the US is just as corrupt, or more, than Brazil.
US may occasionally see third-world-BS, but in many places elsewhere in the world it is a fact of life.
40 billion USD in cash sent to Afghanistan by plane just "vanished". https://www.cnbc.com/id/45031100
For the sake of comparison, the largest corruption scandal of Brazil to this date revolves around 42 billion BRL, which is about 13 billion USD. http://g1.globo.com/pr/parana/noticia/2015/11/pf-estima-que-...
Of course, one might argue "oh, but 40 bilion dollars in cash going missing is not corruption, it's just unfortunate/bad management/insert excuse here". "Corruption" is just one of those words of which the meaning changes depending on the object it refers to - it's always the other person's, never your own.
