That’s very true, but I don’t think he said “black people,” because the audio is very unclear at that point and it seems as if he could have started to say one thing and then decided to say something else. I’m not sure how they got “black people” out of it.
And I don’t even like Santorum because I think he’s a bit of a sanctimonious prig and has no new ideas. But they’re trying to get him for something he didn’t do (even though he would have been absolutely correct - welfare does not improve the lives of blacks).
Sometimes old ideas that were wrongly discarded are the best ones.
