A mini history re: AZ Senate Seat Politics:
McCain was an AZ Senator for 31 yrs over 5 terms.
In 2015 he was primary challenged by Dr. Kelli Ward, an AZ State Senator and tea party fav.
In a surprisingly brutal primary, where McCain poured HUGE 💰 into, he won. (Did he?🤔)
McCain was re-elected Nov 2016. In early 2017, Sen. Jeff Flake looking at his own re-election 2018, it was ugly.
A vocal Never Trumper, MAGA hated Flake and
the Dems finally saw an opportunity to flip a long coveted seat.
Kelli Ward having come close to primarying McCain previously, declared in Oct of '16 her intent to primary Flake for his seat. That looked like the slate: Ward/Flake
Then, in mid July '17: McCain's office released the announcement of his diagnosis with aggressive brain cancer.
