Smart Mobs: Morphing Faces: Hidden Persuaders
You are more likely to vote for a candidate that looks like you – or rather you are more likely to vote for a candidate that you think looks like you no matter what they really look like.

For an example of morphing, check out the Smart Mobs blog post. They posted a couple of examples of faces morphed into the presidential candidates.
