I disagree.
The main target always was and always will be the administration.
This was a tape of a low-level official addressing the NAACP. It's a long way from BO - who, it turned out, was actually given a golden opportunity to look like a hero in outing Breitbart, I mean a big, old softball lobbed right over the plate! but he missed it.
As an Obama hater,
any damage done is always a pleasant thing to see, and in that sense I am enjoying the criticism he is getting for firing her, but Breitbart's motivation was to retaliate for the NAACP's race baiting of the Tea Party, not to embarrass BO. If he happened to do so as collateral damage, then, okay, that's cool, too.
