Chavez's party dominates state polls

President Hugo Chavez, despite an intensifying battle with cancer, has tightened his grip on Venezuela with his party crushing the opposition and winning most governorships in state races Sunday.
Chavez's top rival, Henrique Capriles, survived his own tough test, winning re-election as Miranda state governor. But Chavez's party gained in four other states, said electoral officials in this OPEC nation with the world's top proven oil reserves.
