CARACAS, Venezuela (AFP) — Venezuela is due for elections in 2024. But with no date set, incumbent President Nicolas Maduro coy about a re-election bid and his main rival disqualified from running, nothing much is certain.

This is what we know:

Constitutionally, presidential elections must be held every six years.

The last happened in 2018, boycotted by the Opposition. Maduro was elected for a second, successive term not recognised by dozens of countries and met with a barrage of sanctions.

Then-Opposition chief Juan Guaido was accepted by much of the world as Venezuela’s de facto leader, heading a symbolic “interim government” until January 2022 when it disbanded itself.

As the economy suffered, Maduro withstood the political pressure — holding on with a loyal domestic support base and the military, as well as help from Cuba, Russia, and China.

Then last October, the Government agreed with the Opposition to hold elections in the second half of 2024 with international observers present.

Washington scaled back oil and gas sanctions against Caracas for six months, conditional on a free and fair vote that must include the lifting of candidacy bans on potential opposition rivals.

“The Government was greatly weakened by international isolation,” political analyst Ricardo Rios of the Venezuela Central University (UCV) told AFP.

“It has managed to overcome non-recognition and now needs to maintain a more or less neat image,” he said.

Venezuela’s constitution does not impose a term limit.

In power since 2013, Maduro insists he does not know if he will run, though Diosdado Cabello, the ruling party’s Number 2, has repeatedly stated the incumbent would be the official candidate.

Even though he denies it, Maduro “has been campaigning for more than a year”, said political scientist Luis Salamanca, also with the UCV.

The president was the driving force behind a referendum on Essequibo, an oil-rich territory administered by neighbouring Guyana but claimed by Caracas.

The non-binding referendum was widely seen by analysts as a means of consolidating an increasingly disaffected electorate around a rare unifying theme.

The Government claimed about half of eligible voters turned out and gave overwhelming support for Caracas’s territorial claim to a huge chunk of its neighbour.

Opposition Leader Maria Corina Machado won overwhelming support in a primary vote in October, but is disqualified from holding public office for 15 years.

She was barred by the authorities for alleged corruption and for backing sanctions against Caracas.

Last month, she filed an eleventh-hour appeal against the ban to the Supreme Court, which the Opposition views as subservient to political power.

A ruling is pending.

“If Maria Corina Machado is allowed to participate legally in the elections, there is no doubt she would win,” according to Salamanca.

“But I have many doubts; there is a tendency of the regime to want to stay [in power] and not allow a viable challenger,” he added.

The Opposition has said it would not boycott the election, as it did in 2018, but it is not clear who its candidate will end up being. Guaido has fallen out of favour and is not in the running.

Venezuela is in the grips of an unprecedented economic crisis, with its oil industry all but collapsed and GDP shrinking by 80 per cent in eight years of recession until 2022.

Millions have fled the country in search of a better life elsewhere, many seeking a path to the United States.

Yet Maduro hails his own management of an economy that has shown signs of recent improvement — partly thanks to sanctions easing.
