I sometimes wonder what the Vice President does all day. Basically, he's the spare. If anything happens to the President (JFK, Franklin Roosevelt), the Vice President takes over (Lyndon Johnson, Harry Truman). Also, he presides over the Senate, though I far as I know, that's more of a formality than having any real power. Although in the rare case that the Senate votes 50/50 on something, he casts the deciding vote.
With Cheney, it's a little different. A lot of people speculate (some as a joke, some seriously), that he is quasi the "man behind the curtains", someone with a lot of unseen power and control over the President. He's really more of a background figure, I think, and you don't see him in the media much, and he won't be running for President next year, something VPs very often do (see Al Gore).
Anyway, hope that helped. Gosh, I hope that's all right?
Correct me if I'm wrong, please! It's all I can remember from my social studies class in Jr. High. That, and the preamble to the Constitution, which we were required to memorize in order to pass the class. "We, the peopel of the United States, in order to form a more perfect union,..."
But on the subject of chaos, President Bush visited Vienna last year. Everyone was so angry about this, because they don't really like him, and the whole downtown was closed off, and everyone was late going everywhere. And do you know what they were most angry about?
"And he's only staying for one day!"
