I don't think there is one yet because the AZ GOP have been ignoring him so far. They are stupid peoplle because it will take Goldwater's name reocgnition on top of the issues to defeat Janet. The other candidates won't enjoy a boost in name recognition in the ballot box. This is why we need to run Goldwater because name + issues = defeat for Dems.
Did you hear him on the radio this morning? He really stuck it to Janet and her inaction on getting the Guard on the border.
