Well, assuming this communist expires, what's interesting is who might assume power in Venezuela.
There's this:
But while the president's allies so far appear united, analysts have speculated that differences might emerge between factions led by Nicolas Maduro, Chavez's chosen successor and vice president, and Diosdado Cabello, the president of the National Assembly, who is thought to wield power within the military and who would be in line to temporarily assume the presidency until a new election can be held.
Cabello has dismissed rumors of any discord within the socialist party and issued a Twitter message on Wednesday asserting "the unbreakable will of revolutionary unity."

Maduro's only been veep since October, so he's not been around long. According to this communist's Wiki article, he's a former bus driver and prior to being "selected" as Chavez's veep, was the Minister of Foreign Affairs since 2006, and while that's 'being around', in a dictatorship like Venezuela's that's tantamount to saying Maduro's been in a coma for the past 7 years.
Maduro has no college education of any type, which makes him ideal to take over from Chavez when the bastard finally croaks.

Cabello is a much more interesting character. Slightly younger than Maduro, Cabello has a grad degree in engineering and also is a hard-line communist, having taken part in at least two coup d'états, the first of which earned him a two-year jail term. He's thrown in his lot with Chavez, of course, but despite that, might stand in the way to Cabello's actual assumption of power.
Most dictators/orchestra conductors pick successors who are ever slightly inferior. It's all about the legacy, you know....
