This is an intriguing post and I appreciate all the effort you put into it.

I'd like to go a step further about your talk of elections and accountability. So many districts, I think, are essentially predetermined by the demographics and drawn boundaries of the district. To eject a Democrat from a deep blue seat, let alone a 60-40 seat is nigh impossible (as with a Republican in a rural red district). In fact, it also seems like the seats that do flip tend to flip as a result of new arrivals moving in with different beliefs. The electoral process seems largely disconnected from popular support and approval.
