I think that Palin is letting Ted Cruz operate without her interfering.
Getting Cruz elected in 2012, was a huge breakthrough for her goals of moving the party right.
She has largely reshaped the GOP with her involvement in well over a 100 elections, but Cruz is very much like her, and I think she wants to see him in the White House.
BINGO... she’s keeping her ammo dry until just the right time, they both had what I think was a strategy conference about six to eight months ago, I also think whether or not she has a position in the administration is her choice, she does however seem to enjoy being King Maker and Cruz will need a stout congress in his quest to restore our Free Republic.
