Just for clarification, it appears that when Democrat Congressman Paul Kanjorski, of PA-11, says:
I shared the frustration of my constituents that the war in Iraq continued...I expressed my belief that some Democrats in 2006 overestimated the ability of a single house of Congress to end the war, particularly in the face of an intransigent President and Senate Republicans who are committed to continuing the war
...it actually means, "I'm going to vote for giving the President everything he wants and more in the next Iraq Supplemental I get the chance to vote on."
Thanks for the clarification, Congressman. It's appreciated, not least by your gullible netroot supporters, I'm sure.
