A joke I found:

President Bush was at a meeting and found himself interrupted by a member of the audience who continually shouted: “I vote for the Democrats!”

After a while Bush lost patience and asked : “Well, why do you vote for the Democrats?”

“Why,” the shouting gentleman replied, “My father was a Democrat and my grandfather was a Democrat, and so I am too!”

“Then tell me,” said Bush, “if your father was a fool and your grandfather was a fool, what then?”

“Well, then I’d most likely have voted for Bush!”

Of course, we know this isn’t a true story, because the secret service wouldn’t have let a Democrat within five hundred yards of a Bush event.
