For foreigners:
Venezuela does NOT a parliamentarian system. It has a very extreme case of presidential system and Chávez forced 26 laws last year that allow him basically to completely circumvent any local authority he wants. Besides: he as the head of the petrodollar state, is the one that distributes every single cent of the oil revenues.
Update: and he just said here (Spanish), joking, that he would ask the Chavista governor of Aragua to keep an office for him as the opposition is trying - according to Chávez - to control all of Caracas. This reminds me very strongly: do you know who else had a love for ruling from Aragua? This one
And I told you so here.
