You may recall from past posts my absolute hatred of "Democratic Unity" events with a "pay at the door" policy. Simply put, you can't claim to represent all your constituents when your events are only open to those who can afford them.
As it turns out, it appears I have a kindred soul in this feeling in Nick Johnson, who has a great post up comparing Harkin's Steak Fry (elite only) to State Senator Bob Dvorsky's birthday party (all welcome).
I recognize candidates need money, but there's a correct and an incorrect way to ask for it. Nick has the details.
