Ray Long and John Chase in their Chicago Tribune article here call the issue "a technical problem with Illinois election law" in their otherwise great run-down of the ethics reform triumph.
There's nothing technical about a deadline that is knowingly violated a year and a half ahead of time in order to exploit the 9/11 tragedy. This wasn't a mistake. This was an arrogant decision by the Bush campaign to go ahead and break a dozen or so state laws and assume that the states would roll over -- that's how hungry they are to use the anniversary of the attacks to help the Bush campaign. It's dishonorable. It's worse than the fighter pilot costume with the military-as-prop stunt. This convention will be the mass-grave-as-prop stunt.
