SlackerInc.'s useful diary regarding taxes leads me to thinking that another DailyKos demographic poll is in order.
This one is about income. A few definitions are in order. Please base the number on your household's income. In this case, I would count as a household you and your spouse or partner (if in a marriage type relationship but not married) but other types of roommates.
Please also note special categories for students as I didn't want to skew the results, knowing how many students are here.
