“Never heard of that before, now did ya? /s”
It works in some districts, not in every district. As I recall it was tried against Paul Ryan in 2016 and failed miserably.
It was only employed when Nehlen entered the race and he even admits he was way to late. If you go back and study the Brat campaign, Nehlen’s was only on media splash. Go back and study what Brat did and you will see the big difference. This is evidenced at how Nehlen has been in the race officially for a few months now and doing the groundwork in the district that he did not so before.
