The onslaught against Henrique Capriles Radonsky by Venezuelan state-run media has begun after his decisive victory in Sunday’s presidential primary. Capriles is now the nominee of the opposition coalition and he will face Hugo Chávez in October’s presidential election. As the Wall Street Journal reports, the vicious attacks against Capriles include, among other things, insinuations that he was a homosexual and that he is a Zionist agent.

This election will not be a fair one. Not only does Chávez control most of the Venezuelan media, but his government is also dramatically increasing spending on popular social programs. About 8.5 million Venezuelans already receive some kind of permanent income or assistance from the government (4 million of them are public employees). The Chávez regime threatens and intimidates those who receive government handouts and dare to support the opposition. Moreover, since voting is electronic in Venezuela, many people fear—perhaps with good reason—that their votes aren’t secret. The government tacitly encourages these perceptions.

But that’s not the end of the story. Chávez also controls Venezuela’s National Electoral Council. Due to the inability of the opposition to monitor every voting station in the country, the stated results of the vote may not be accurate. The Electoral Council usually takes longer than is necessary to tabulate voting results from electronic systems, which has raised concerns of fraudulent activity.

A main concern is the electoral registry, as documented by Gustavo Coronel in a Cato study back in 2006. Coronel wrote that an independent analysis of the electoral registry found many irregularities:

such as the existence of 39,000 voters over one hundred years old. This is a number equal to that of the same age group in the United States, where the population is 10 times greater. Of these 39,000 people, 17,000 were born in the 19th century, and one is 175 years old and still working! Nineteen thousand voters were born the same day and year in the state of Zulia. There are thousands of people sharing the same address.

So on top of the support of his followers (some enthusiastic, others intimidated), which fluctuates around 45 percent of the population, Chávez can also rely on a margin of error due to electoral fraud if he doesn’t get enough votes for his reelection. I’ve talked to some Venezuelans who say this margin can be as high as eight percentage points. That is, if the election is decided by less than that (very likely the case), Chávez can doctor the results in his favor.

The opposition promises to have people in every single voting station in the country watching the vote. The National Electoral Council will probably bar international observers from monitoring the election. This sets up the potential for conflicting results from the opposition and the National Electoral council. What would happen next is anyone’s guess.
