"Clinton says insurgency is failing", Associated Press, February 19, 2005:

As 55 people died in Iraq on Saturday, the holiest day on the Shiite Muslim religious calendar, Sen. Hillary Clinton said that much of Iraq was "functioning quite well" and that the rash of suicide attacks was a sign that the insurgency was failing.

I'll just observe that I don't think that take on things has been borne out by the subsequent years.
