Every dictator--hell, every national leader--does some good things and some bad. They will make some friends among the population, and some enemies. To ask those who fled what they think is rather one-sided; why do you think they fled in the first place?
But in this case, on ballance I think Chavez comes out very heavily in the red. He was not a good person, and took glee in shoving a stick in the US's eye.
But what I think is interesting, this is really a very mild preview of the discussion (yelling match?) we'll see played out when the Castro dynasty finally goes away. I'm sure castro is even farther down the list of evil people to many of the posters here. But he also did some amazingly good things for a lot of Cubans post Batista. The definitive biography of Fidel will take a very long time to eventually be written, and even then it will probably be a lot of fiction. Chavez was only a very, very small reflection of that.
It will be interesting to watch a melt-down of Chernobyl proportions on here. I should start stocking up on popcorn now.
