I think we cannot blame Carter or Gaviria, they pretty much did their job. There is not proof, simply because this is something that was planned by the Government and the CNE, when the so called referee manipulates everything to his will, how can you prove there was something out of the ordinary?
I agree that the US and the international community in general preferred to ignore the fraud allegations, and that they did it because it worked to their convenience but honestly, what have we done to really demonstrate that there was a fraud? nothing. And not because we are stupid or incompetent, though some opposition leaders might very well fall into that category, it is because we cannot prove something that was prepared as flawlessly as this fraud was.
but we are sure the fraud was there. I mean, hello? Chavez with almost 6 million supporters? yeah, riiiight. If the CNE had told me, hey the dude won by 5 points, I would have accepted it, it is possible why not? But that they come here and tell me that the most hated person in Venezuela won by a margin of 20 points, come on! that was just silly.
