The New York Times reports that, "Arizona’s Democratic Party has filed a formal complaint with local, state and federal prosecutors in an effort to have the candidates removed from the ballot, and the Green Party has urged its supporters to steer clear of the rogue candidates. The Democratic Party is fuming over (the Republicans) tactics ... The Green Party does not have the resources to put candidates on ballots around the state and thus creates the opportunity for write-in contenders like the (homeless straw candidates) to easily win primaries and get their names on the ballot for November. Complaints about spurious candidates have cropped up often before, though never involving an entire roster of candidates drawn from a group of street people."
The Arizona Republican party is known for dirty tricks and for voter suppression. The late US Supreme Court Justice William Rehnquist, back when he was a Republican political operative in Arizona, was a notorious political dirty trickster, leading voter suppression campaigns to keep African-Americans and Latinos from voting.
