The best thing we've done is help the Iraqis here get their voices heard by the American people. The rally in Oct. 2002 that C-SPAN showed was a eye-opener for alot of people as to how bad things were in Iraq.
While the coverage of these polling places in the US was fairly extensive and of positive effect, I don't know that I ever saw them mention that the cost was paid for by Iraq. It somehow makes it an even more sterling effort.
