The Cernovich thing was a hail mary for Ward; she knew she was pretty much toast. I feel bad for Ward since I think she was the best candidate but once McSally ran that ad with Trump praising her (even though it sounded like it was spliced together) it was pretty much over at that point. Arpaio was a non-factor.
Yeah they have exposed themselves to us, but how many Arizonans even know who Cernovich is or that he is a fraud? Relatively few I would assume. I doubt Kelli Ward even knew much about him but was desperate for any help she could get because she had no money or backing. That's why
I say you shouldn't read too much into Ward going around with Cernovich.
