Just a quick thought...

It's easy to tell is a politician, who's giving a speech, is lying. Just check to see if their lips are moving. It's a little trickier to judge political ads.

However, I have come up with a way to judge if a political ad is attempting to deceive me. If they show their opponent in a grainy, distorted, unflattering video, they must be lying. If your confident in your position you don't have to resort to such silly, ignorant, juvinile antics.
