For as long as there have been politicians, they have lied, fabricated and deceived. The manufacture of falsehood has changed over time, as the machinery becomes more sophisticated.

However, even if honesty is sometimes the best policy, politics is addressed to people’s opinions, and the manipulation of opinion is what it is all about.
