All those affected by 9/11 = a special interest group?
Well, they're not a general interest group, like all taxpayers or all citizens. They are a group of people who have a particular interest not shared with the rest of the public - so as loosely defined, I guess so (and, as far as I remember, it's not all those who are affected by 9/11 who benefit under the bill, largely first responders). But they're not an inherently Democratic special interest group, or what in particular I was talking about.
I was talking more about DADT, the DREAM act, the various paycheck (supposed) fairness acts, card check, etc.
