It is wrong for someone claiming to be a spiritual leader to be calling for assassination of legitimate heads of state. It's no better than if he was Mullah Robertson. Of course, Robertson's brand of religious fanatacism is what McCain spoke out against and took a drubbing for from the GOP voters.

Chavez is a bit nuts, and I don't like his politics (despite wanting to see reform), but unless he does some things that clearly put him out in former Qaddafi/Saddam territory, calling for his assassination is going a bit far.
