“She filled out McCain’s term, so this cycle she’s running on her own ticket, for a six-year term.”
McCain won the seat in 2016. He died on 25 Aug 2018. Jon Kyle was appointed to replace him.
McSally ran for the open seat in 2018 and lost to Sinema. She was appointed in December 2018 to replace Jon Kyle, who had resigned from the McCain seat. So the McCain seat went to Kyle, then to McSally, and now McSally is running to finish it out.
That is my understanding. I’m open to correction if I’ve followed it incorrectly.
Yes, I think you’re right.
