It's not the first time Jones tried to run in this district. Two years ago, the local GOP was "saved" by the fact that Jones' signatures partly were out of district and thus void (he also tried to run for Senate and used signatures collected for that for his House bid). So the local GOP was forewarned.
The GOP doesn't stand a chance to win that district anyway, so how hard would it have been to get someone to nominally run for a position they wouldn't get anyway? Cue scene from the AGM:
"Next item on the agenda. Nominate a non-Nazi House candidate. As you all know, Nazi Arthur Jones has been trying to run in the GOP primaries for the last five House elections, and he'll undoubtedly try to run again. So we need a warm body on the ballot who will run against him to save us from the disgrace of having a Nazi on the ballot come November. In the board, we've been drawing straws and our beloved treasurer, mr. X. Torter, has drawn the short straw. We need 603 signatures to get him on the ballot, so we're now passing the paperwork around for his support signatures. Please all sign."
Really, how hard is it?
