State by state:
I could even understand Chavez winning in Carabobo but Zulia?

During the Parliamentary elections in 2010 Chávez only got 3 out of 15 seats from Zulia and less than 45% of the votes there, every Venezuelan knows opposition candidates always win in Zulia

Chavez won in Zulia by a wider margin than he won in Bolivar, a state that was usually supportive of him.
Lara, Miranda and Nueva Esparta their results

nnnnn not a 743 vote lead for Chavez in Miranda

The very same state Capriles is governor of.
