Later today, Venezuelans will go to the polls to re-elect President Hugo Chavez, or to replace him with his centre-right competitor, Henrique Capriles. Chazez, the self-proclaimed "socialist for the 21st century", has been in power for 13 years. But he is facing strong competition from Capriles. Critics say the election campaign has been unbalanced and voters have been intimidated. RFI spoke to Hector Faundez Ledesma, a professor at the Central University of Venezuela who has been following the election closely.
