It’s not just that his comments were foolish on the merits. They would seem to demonstrate that he’s completely incompetent. I’m pretty dubious about the efficacy of the “Sister Souljah” routine in any case, but in this specific case it’s all downside and no upside. How many of the low-information centrist voters who are hypothetically supposed to find attacks on liberal activists pleasing read the Hill or the blogs that would discuss it? The audience being attacked is the only audience who cares and is paying any attention. And the non-walkback walkback certainly doesn’t help anything.
We need our own Ari Fleischer; even if he can’t be as accomplished a liar, at least he’d know to keep his focus on his actual enemies.
