Obama claims Clinton won't admit that on Social Security, there's "an actuarial gap that has to be dealt with." She's too afraid of adopting "Republican talking points" he says. She tries to rise above this, responding that there's isn't a great difference between her and Obama on Social Security, except that she articulates, again and again, that "fiscal responsibility" can't happen "on the backs" of the elderly or middle class. That seems like a good line to me. --Dana Goldstein
