Dist. 1 is not in Maricopa Co. and wr not included. Though part of Dist. 7 is and they didn't do that one either.
I know Nick Coons was supposed to be there for Dist. 5 later, but don't know if he showed up. I do not know if the Libertarian candidate from Dist. 6 was invited, but D-6 was scheduled later on as well.
I hope Thomas has the full responses of Mike Shone as well, as I would like to post them. Though I do like the special 911 confrontation with incumbent Congressman Ed Pastor (D-AZ4).
