McSally was a dumb appointment. She lost the election, appointing her in hopes she would do better the next time was foolish IMHO.
Not if you are Doug Ducey and want to keep the seat open for yourself in 2022.
Someone like Rep. Andy Biggs would be beating Kelly like a redheaded stepchild by now - but his presence would also close the door to any "McCain Moderates" hoping to regain control of that seat in the future.
