Brazil is more likely to go supra-right than supra-left. Hell, it's already leftist, so the only way it could change would be to swing rightward. Lula is a career dissenter who, if elected, won't know which shoe to put on first. He will be squashed. The only way he could survive is to pretend not to be the commie that he is.
The author of this article is pissing hysteria. The danger of Lula is real, but it is not a danger of revolution. Not even Chavez can get away with that.
Now, if Brazil goes, it goes the way of Cuba, not Chile. Castro was much smarter than Allende, and more devious. Fidel played cute for a few years before pulling the trigger. I don't count Lula in either category.
Vigilence, nevertheless.
[Chavez has already driven up real estate prices in Miami. If Lula wins, it'll be even more of a seller's market... Careful, though: the NASDAQ is A-ball to a real FLA real estate game.]
