Sinema was pressured by the business interests afraid of the Democrats being too powerful.
These same Mothers Of Business want to destroy President Donald J. Trump so they boycotted his candidates in the Mid-Terms and ended up with bag they hold.
They needed to switch gears and wean Sinema away from the Dems.
Two things.
If Sinema goes away from the Dems, she’s gone. They’re already looking to replace her and with Hobbs there, the Democrat is a lock
This is all a stunt and she’s as much and independent as sanders and king.
