Calling all idiots!

Mr. or Ms. Narcissist is successful in controlling others because if they aren't they simply move on to someone else or groups of someone else's. The non players are side stepped, ignored, avoided or vilified as the case may be...everyone else is left to serve as their useful idiot.

Pity for the Boot Licker?

Narcissist's don't have "friends" they surround themselves with Syc·o·phants and other boot lickers.

/ˈsikəfənt,-ˌfant/

1. a person who acts obsequiously toward someone deemed as important in order to gain an advantage 
2. a servile self-seeking flatterer 

What would you call the people that cling to narcissists despite evidence to suggest that they will be used, exploited and abused?
