haha, I love that comment, but (other than a large number of American politicians) I think, worldwide, most politicians are not stupid but move between a range disingenuity and outright liars. Of course, any of them will move within that range depending on the topic and benefit to that individual politician.
The more I follow American politics the more shocked I am with the number of apparently dangerously stupid people elected to positions of power in America. Some of them are, certainly, just disingenuous liars but watching this political space closely it appears that some, maybe many, really are quite stupid. This does not bode well for our future as a species.
