Flake can’t be Cantored because he’s about to retire. McSally-R and Sinema-D are running for that seat.
As unbelievable as it may seem Flake might actually be working with Trump and the Republicans in the runup to the midterm. Complacency is the enemy of the incumbent party in offyear elections. Angry voters hit the polls. Flake is insuring that AZ Trump voters are furious.
Nice take.
