Redoing the election only takes pressure off Maduro. It’s an empty gesture to appease the opposition for a time, which just gives Maduro room to plan for stealing the next election. And it drags things out for longer, which can easily cause some of the energy to be drained from his opposition, because movements like this tend to fade out after a while.
And what could possibly be the point? If he won’t concede this time, next time won’t be any different.
They know that. That’s exactly the point of trying to deflect and downplay this whole fiasco.
