I never understood what he was doing in the race. How many terms can he serve even if he wins? His 2 cents are best rendered with an endorsement of the candidate most like him. We have seen a side of Arpaio - an ego unconstrained by a concern for the greater good - that is very unflattering to him.
At age 75 I can say this without being legitimately deemed ageist: Joe Arpiao, great guy and great conservative that he is, is, at age 84, too old for the job. That leaves Kelli Ward, in whose favor he should drop out.
