Indeed, Arizona has many good choices, with Trent Franks, Dave Schweikert, Paul Goser and ex-Rep. Matt Salmon (although he might be done with elected politics) all possibilities. Treasurer Jeff DeWit is floated as a possibility too, although I really don’t know much about him.
All I know of DeWit, he supported Trump, he ran unopposed so he hasn’t faced a democrat statewide (or at all) before.
And according to an article I read he backed state democrats on education funding which is hella lame.
