Red herring:
The fallacy of raising an irrelevant issue to draw attention away from the real issue

Example:
"We admit that this measure is popular. But we also urge you to note that there are so many bond issues on this ballot that the whole thing is getting ridiculous."

-Tax cut commercial

Explanation:

Red herring is used a lot in politics. The purpose of it is to simple draw attention from the real issue being discussed. Politicians do this to avoid people finding out about certain things they don't want people to know.     This same concept can be applied to literature, authors do this to characterize a character, or even stir the reader away from the real issue.
