This comment from Rudy Giuliani is being reported as news, for some reason.
I have never seen a vice president that has made as many mistakes, said as many stupid things. I mean, there’s a real fear if, God forbid, he ever had to be entrusted with the presidency, whether he really has the mental capacity to handle it. This guy just isn’t bright. He’s never been bright. He isn’t bright. And people think, well, he just talks a little bit too much. Actually, he’s just not very smart
A little background. In the pre-caucus phase of the 2008 presidential primaries, Joe Biden was getting zero traction. Rudy Giuliani was steadily losing it. Biden was the chairman of the Senate Foreign Relations Committee; Giuliani traded, then borrowed, then mortgaged off of his reputation as America's Mayor. So Biden liked to rib Giuliani about his ignorance. One example:
Flash cut to four years later. Giuliani is a vastly diminished figure whose consulting/speaking business has only slowly recovered from his 2008 disaster. Biden is vice president. You can see why the former mayor would kick and scream a little.
