In an article about Obama's governing style, the Times addresses Clinton as SoS and reports [emphasis added]:
During the battle for the Democratic presidential nomination, Mr. Obama and Mrs. Clinton went out of their way to point out their foreign policy differences, with Mrs. Clinton portraying herself as a hawkish Democrat and defending her decision to vote in favor of the 2002 resolution that Mr. Bush later considered an authorization to use military force against Saddam Hussein. (Later, she said she fully expected Mr. Bush to use diplomacy first - and was shocked that he did not.)
NPR from March, 2008:
Clinton has said many times since that she regrets her vote and that she would vote differently knowing what she knows now, but she has never apologized for position in 2002 (although other Democrats have).
