An excerpt from an interview with Gore Vidal (in Scoop) in regards to the State of the Union:

I had a piece on the internet some of you may have seen a few days ago, and there's a story about Tiberius, who’s one of my favorite Roman emperors. He's had a very bad press, because the wrong people perhaps have written history. But when he became emperor, the Senate of Rome sent him congratulations with the comment, “Any law that you want us to pass, we shall do so automatically.” And he sent a message back. He said, “This is outrageous! Suppose I go mad. Suppose I don't know what I'm doing. Suppose I'm dead and somebody is pretending to be me. Never do that! Never accept something like preemptive war,” which luckily the Senate did not propose preemptive wars against places they didn't like. But Mr. Bush has done that.

... I'm trying to track down this 'piece on the internet' ... [i keep coming across different versions of this State of the Union thing]
