I am not so “concerned”.
Cruz is done. No intelligent political operative is tying their own future to Cruz’s wagon. If Kellyanne wants a future (and she does) then she will work hatd for Trump’s success.
As far as I can see, she’s doing fine.
Unfortunately, I think Ted Cruz is the Ryan Lochte of the GOP, at least for a few years. Persona Non Grata. Chris Christie is probably glad to have someone else occupy the proverbial ‘doghouse’.
