Why do Democrats like Murtha apologize for War in Iraq?

[Filius Nullius]

Why do Kerry, Murtha and other Senate and House Democrats routinely apologize for voting "for" the war in Iraq? I heard Murtha do it again on CNN earlier this evening. I thought that they actually voted to give President Bush authority to decide whether WMD existed in Iraq and whether he should therefore commit U.S. forces to a war in Iraq. Do they still think the U.S. public is too stupid to understand the difference between voting for war and voting to allow the President to decide? If they want to apologize for something, apologize for delegating authority to an incompetent like Bush to make the decision, not for actually deciding to go to war.
