Wednesday Open Thread: Headline in WaPo: Hollywood Gives Obama Both Cash and Credibility

I understand the cash reference, but...credibility? Read all about it here.
Excerpt here:

Movie stars Tom Hanks, Jennifer Aniston and Denzel Washington wrote checks, and scores of producers and agents paid $4,600 per couple -- the maximum allowed -- to jam a hotel ballroom for a two-hour, closed-door cocktail reception hosted by entertainment moguls Steven Spielberg, Jeffrey Katzenberg and David Geffen.

Ok, still confused here. Where's the credibility part of the story?
