Why won't anyone run against these idiots?

Sen. Thayer Verschoor, Rep. Andy Biggs and Rep. Eddie Farnsworth are all running for re-election in the district, which covers Gilbert, parts of Mesa, Queen Creek, Apache Junction and Gold Canyon. All three Republicans are unopposed in their respective races.

Isn't there a sane Republican somewhere in the vicinity who can save us from this folly? Is it too late to run as a write in?
