A good commentary by Bob Garfield on why doesn't KFC just embrace who they are, and try a little honesty in it's advertising. For those who haven't heard KFC is donating money for every pink bucket of chicken you buy. Stunts like this don't work precisely because they are stunts that don't connect with any deeper meaning. What does KFC stand for? I don't know, do you? Does KFC? What do they have to do with breast cancer? No idea.
This is akin to a campaign throwing an issue out there just because it scored well in a poll. It all has to have some deeper meaning, some connection to make sense in the mind of voters or it's just another stunt.
