This morning I remembered reading, when I was a kid, a short novel (maybe by Asimov) about a guy in a not so distant future who had been selected as "the voter". Computer technology and had evolved so much that a computer could simply make the decision about who should rule the world. A super computer (the Multivac if it was Asimov) could do all the statistical analysis necessary and decide, it only needed the input from a single human being.

The good news is that we didn't get to this point, the bad news is that we are not so far.

We don't have a single voter, but we have a single country electing a person who can significantly impact the whole world: the United States of America.

Most Americans don't seem to realize this; to the contrary they often seem to be one of the democratic peoples less aware about what's going on in the rest of the world.
