If you're looking to place blame though, I would start with the AZ Gov and Sec of State
I blame the entire process. Every person involved. On both sides of the aisle, in the media, and every where in between.
1. Why are politicians okay with accepting exit polls as official results in many, many elections? It is an insult to the people and their right to vote. Politicians of every party should demand that every vote be counted, even if someone is going to win 90-10.
2. Why is the media allowed to run the narrative in this country? When Romney took time to concede, he was berated on air like he was scum. Let the process work itself out.
3. Why do we as citizens allow this pony show to continue?
We are all at fault.
