Iván Duque, the former president of Colombia, indirectly put forth an interesting proposal. It was mostly a warning, but hypothetically gives Maduro the room to bow out gracefully later this year. Duque warned that the Venezuelan court system was preparing to invalidate the election results citing foreign interference and hacking. It is worth stressing that even Kaspersky, a Russian cyber security giant which has been sanctioned by the United States for its ties to the Kremlin, stated that there were no notable attacks. I should note, I have personal sources outside of the United States government who have independently been able to verify that Kaspersky acts as an arm of the Kremlin; so this is effectively Russia going against their own ally. Anyway, the court would invalidate the election and then have a new one held in December. During this time, Maduro's government would intensify efforts to both win over votes and to further suppress the opposition, and win "legitimately" in December.
A more optimistic reading of this (not that I think it's warranted, just putting it out there) is that this would allow Maduro to save face and stand aside in December. He could claim the data showed he won, but citing the claimed irregularities, he wanted a redo, which he would respect the results of. I don't see this happening, but Duque's warning is still (indirectly) the first compromise position that has been floated. A pessimist reading is that this simply buys time for detractors of Maduro to quietly try to ignore the problem while tacitly accepting he'll be remaining in power.
Protests continued for another day today, but there were no significant developments in that regard. Basically, just more of the same, which isn't enough to move the needle in favor of the opposition at all yet.
