He endorsed Vernon Parker(anchor baby supporter claiming to be an immigration hardliner) and La Raza Rick for 2012 among others.
His good endorsements were JD Hayworth and incumbent AG Tom Horne who lost to the Jon Kyl puppet Brnovich.
In some of the House races McCain's endorsements haven't worked out for RINOS like Quayle, Paton and Kirk Adams.

Joe Arpaio: My endorsements more effective than John McCain's

It appears there’s confusion about Jeff Sessions, and Pete Sessions.
Pete Sessions is a total amnesty loving RINO. Sherrif Joe has been played.
This is from March 1, 2014.
Why is it relevant now?
Very interesting dynamics. Thanks for posting. HOORAY Jeff Sessions and Sheriff Joe.
Um, Coal, the Texas primary is ancient history.
But anyway, I’ll never forgive the Sheriff for endorsing JANET NAPALINTANO (D) for Governor in 2002.
I have the highest regard for Sheriff Joe, but you are right that he has picked some rotten eggs at times.
Certainly Pete Sessions is an amnesty whore.
Sessions won re-election to the U.S. House in 2014. He defeated Katrina Pierson in the Republican primary on March 4, 2014. He defeated Frank Perez (D) and Ed Rankin (L) in the general election on November 4, 2014.
