The world of politics is never pretty and often very ugly.

One of the most ugly features is how the politicians switch facts around to protect their argument.  They determine a conclusion that fits their needs, and then find the facts that support their conclusion, almost an intellectual reverse engineering.

It's not all that hard, we teach it in every school that has a debate team.  You are assigned a topic, and have to develop an argument to support it.  The validity or accuracy of the facts you present is unimportant unless they are challenged by your opponent.  Preparation becomes the driving factor: are you able to anticipate the challenges and overcome them?  The bottom line is that in the end, the facts don't matter.  Just the Feel.  Can you offer convincing sincerity?  Confidence?  Can you sway them with an emotional plea?  All powerful weapons.
