2013 Early Venezuela Presidential Election

[Absentee Voting Ghost of Ruin]

So who's acting president? Cabello or Maduro?

Cabello, until the election, from everything I can find on current Venezuelan succession law. The law had already been bent (with the active co-operation of Cabello and the Supreme Court) to allow Chavez to skip his inauguration, so I suppose another twist to put Maduro in charge isn't out of the question, presuming Cabello would support it. I don't see why he would though, assuming the two are in fact rivals.
