Fourth question

I didn't really understand the question Stephanopoulos asked. Was it about errors? Once again, Obama takes the high road, saying that it's a "mistake" to "obsess" about the errors, like his about bitterness and Hillary's about Bosnia.

(That reminds me: Hillary acknowledged in her response that 1) she knew what she said about Bosnia was wrong when she said it, and 2) she acnkowledged about people are bitter! Hello??)
