The seat will definitely go to a Republican and Ducey has said he will not appoint himself.

His chief-of-staff Kirk Adams is a strong contender for the role, as are other prominent Republicans in the state.

However, it is not just Rivera who has suggested Mrs. McCain take the seat.

According to CNN, “Another option Arizona Republicans raised includes Cindy McCain, John McCain’s wife, who is also chairwoman of her family’s beer distribution business and an advocate against human trafficking who has filled in for her husband at public events at times after his diagnosis.”
