It is possible to love Trump and not like some of his picks.
Yes. Because remember Bannon the honey badger is in his ear every day.
Trump hasn't picked Romney for anything yet!
My opinion is that the meeting was held as a courtesy and for public relations purposes. By at least creating the appearance that Romney is being considered for a high post, he (Romney) has been de-fanged as a possible Trump enemy going forward and it cannot be said that Trump did not consider establishment moderates for his Cabinet.
I would be shocked if Romney was offered a high level post like SoS. He might be offered a lower level post where he can't do much damage.
