Read the text of the scathing letter OAS Secretary General Luis Almagro wrote to Tibisay Lucena, the president of the Venezuelan National Electoral Council. Adam Isacson noted approvingly on Twitter that it even quotes Bob Marley. But it goes into extensive detail about problems in Venezuela, and maintains a critical but not aggressive tone.
This part struck me especially:
It has been some time in our region since a top opposition figure was imprisoned around the time of an election. The last such case was that of Wilson Ferreira Aldunate in Uruguay in 1984.
At that time Uruguay was still a military dictatorship. That's not the sort of company you want to be in.
