In spite of efforts from Venezuela at the OAS to block the invitation of the SUMATE ONG to an OAS meeting, the council went ahead and ratified that SUMATE was invited along a few other Venezuelan ONG. The excuse presented by Venezuela's ambassador to block the invitation of SUMATE because this one was involved in events of 2002 was rather lame as SUMATE in those days barely existed. But of course the real reason is that chavismo cannot forgive that SUMATE organized the successful Recall Election drive in spite of ALL THE ABUSES committed by chavismo to derail the effort (and their own failure at raising a credible recall election for opposition assemblymen).
I think that Valero sensed the exasperation of his colleagues as he decided at the last minute to back down to avoid a full frontal vote second vote that would have established the growing isolation of Venezuela in the OAS.
The good news there is that the problems of the electoral system in Venezuela are now been noticed outside and SUMATE is considered as one of the best defender of the right to vote, and certainly technically the most informed one. Let's hope that this well deserved recognition of Maria Corina Machado and SUMATE's work will boost the growing movement inside Venezuela to put due pressure on the obscenely partial CNE.
