This is an opinion piece that criticizes the nature of political campaigns. The author uses the word "whitening" as a metaphor to describe how candidates in elections attempt to erase their past, hide mistakes, and soften contradictions during the campaign period.
The article suggests that some stains from candidates' pasts disappear completely through this whitening attempt, while others become even more visible when exposed to good public scrutiny.
The text mentions "O Matuto," a reference that may be to a character or public figure, and Cicero, the famous Roman politician and orator, questioning whether politics has truly improved since the times of Ancient Rome.
The author concludes that the contemporary political campaign functions as a whitening exercise, where candidates attempt to present a purified image of themselves, regardless of the reality of their political history.
