This is just a little taste meant to get Geffen's attention. Hillary doesn't want to destroy him just yet - she just wants him the "see the error of his ways" and come back onto the plantation before it's too late. She still wants his money and influence within Hollywood.
Of course, if he continues to support Obama, Hillary will try to finish him off for good at a later time.
Which is a good reason to take all their money away from them.
