How can religious figures, such as Pat Robertson, preach against democratically elected heads of state?

Take that Robertson, who speaks "in the name of" some kind of what he views as God. How can he preach against democratically elected (and I mean without using the false propaganda portraying political rivals as "Nazis" and Jews as their "only" victims) heads of states such as Milosevic, may God avenge his death, who (unfortunately) wasn't a tough head of state or nationalist at all, but did (sometimes) help his people against the worst kind of terror, or Hugo Chavez, who rightly oppose today's best example of m oppression-US imperialism & exploitation of the unfortunate? The same question applies to "Rabbi" Simcha Cook.
