Valid question, but I think it was simply to see how they faired in the midterm elections.
They knew a lot of people support the Bush tax cuts... including those who will not be effected by the proposal to keep them enabled for all but the top 2 percent.
I find that interesting as well.
I truly have no idea, but I don't understand why someone who makes 40K gives a damn about someone making 450K either.
Just comes across as weird.
