I must be blind; I saw no clear support for him being a dictator. One group says clean elections (the well respected Carter Center in fact) the other group says fixed. (the group appears to be a for hire Political consulting group, not a non-profit, their reputation appears to be controversial)
Were you just providing a link or trying to prove he Chavez is a dictator? If the latter, I think you failed, if the first, Wiki is not a great authority, but only a good jumping off point.
There is no question he is anti-American, I just do not see the label Dictator as being fair. Would America be better off with a Pro-American President, of course, but lets be honest in the debate at least. The reason to dislike Chavez is he is an irritant to the US and our policies, not that he is a Dictator or in anyway worse than dozens of foreign leaders we have supported in the past and present.
