Whether Chavez can be removed from office alive is a very open question at this point.
I feel it is very likely chavez is in for the duration at this point.
Of course, Venezuela elected him in 1998, KNOWING he wasn't in favor of rule of law, orderly transfers of power, etc. Their frustration with their traditional oligarchies was such that they put an ideologue in power, re-elected him in 2000 after he gutted their constitution, and then spectacularly managed to depose and re-instate him in 2002(?) when the opposition proved it was just incompetent. I don't regard the 2004 referendum as representative, given the comments about machine fraud. I have no idea of the truth, of course, but if carter supports him it cannot be good.
They asked for it, and they have got it. I assume the US has given up on this also...it is almost impossible to unseat a sitting dictator, as was made evident with the 3-year melodrama of trying to get Noriega out of power in Panama, where the US already had 10's of thousands of soldiers a few miles from his headquarters.
