Venezuelans vote Sunday in regional elections to determine more than 20 governorships and 300 municipal posts.

President Hugo Chavez has expressed confidence his supporters will win a majority of the positions.

His opponents are considered to be divided since the head of state won a recall referendum vote in August.

The challengers said the balloting was rigged and they have continued to protest, although international observers say there was no evidence of cheating.
